HUMPHREYS, Judge.
Sebastian Cortez-Hernandez (“Cortez-Hernandez”) appeals his convictions in the Circuit Court of Prince William County (“trial court”) on one count of first-degree murder, in violation [71]*71of Code § 18.2-32, and one count of use of a firearm in the commission of a felony, in violation of Code § 18.2-53.1. Cortez-Hernandez asserts the trial court erred in refusing him the opportunity to re-cross-examine a prosecution witness after the Commonwealth’s re-direct examination of that witness. Cortez-Hernandez also alleges the trial court erred in refusing to grant jury instructions on excusable self-defense and voluntary manslaughter. For the following reasons, we affirm the trial court.
I. Background
During the second week of May 2008, Omar Yasquez (“Omar”) got into a fistfight with Santos Ontiveros (“Santos”). After besting Santos, Omar went into El Mexicano Restaurant in the Georgetown South Shopping Center to wait for his brother, Ruben, to pick him up. When Ruben arrived, the two drove off toward Omar’s residence in the Georgetown South housing community (“Georgetown South”). Before they got to Omar’s residence, however, Cortez-Hernandez, Santos, and another individual intercepted them by standing in front of their vehicle, blocking the street. As Omar and Ruben exited the vehicle, Omar got punched in the face. A fight ensued, and Omar was beaten “pretty badly.”
A few weeks later, on May 31, 2008, Cortez-Hernandez and Santos dined with a group of friends at El Mexicano Restaurant in the Georgetown South Shopping Center. At the same time, Omar congregated with his cousin and friends in front of Mike’s Quick Mart, also in the Georgetown South Shopping Center. They planned to dine at El Mexicano Restaurant, but when Omar realized the individuals from the previous altercation were inside, he called Ruben to pick them up.
When Cortez-Hernandez found out Omar and his friends were outside, he called a friend to bring him a gun. When the friend arrived, Cortez-Hernandez stashed the .45 caliber gun in his pants. Shortly thereafter, he and his friends exited the restaurant and proceeded down the sidewalk past Omar and his companions, down Grant Avenue and toward Georgetown South. Omar and his friends, also residents at Georgetown [72]*72South, decided to walk home in the same direction. Along the way, Omar picked up a stick and gave it to his brother, Ruben. When they reached Grant Avenue, Santos came from behind Omar and punched him in the nose. Omar grabbed his face as blood poured out of his nose. Ruben hit Santos with the stick before Santos could hit Omar a second time. Santos ran toward his group, comprised of nine individuals, and one of them responded by charging toward Omar and Ruben with a knife. Ruben again raised the stick to ward him off.
At that point, Cortez-Hernandez positioned himself behind a large tree in a nearby yard and took out his gun. All of a sudden, he lifted up his shirt, yelled, “Que vale mierdas,”1 then, fired four shots, hitting Omar twice. Ruben called 911 and waited for help while Cortez-Hernandez and his friends fled. Paramedics arrived and announced Omar dead at the scene. The autopsy revealed that Omar had been shot twice, and the kill shot had traveled through his lung, heart, aorta, esophagus and vertebra before lodging in his lower left back. The bullets found in Omar’s body were traced to Cortez-Hernandez’s .45 caliber gun, and Omar’s blood was found “ten to fifteen feet” from the tree behind which Cortez-Hernandez had been standing during the altercation.
Cortez-Hernandez was indicted and tried by a jury for first-degree murder and use of a firearm during the commission of a felony. Hermenjildo Rivera (“Rivera”), an eyewitness and friend of the decedent, testified during the Commonwealth’s case-in-chief. During re-direct examination, the Commonwealth asked Rivera for the first time about the fight and the shooting. Defense counsel objected, arguing the Commonwealth exceeded the scope of direct and cross. The Commonwealth offered to “relieve [Rivera] and re-call him back.” Without comment, the trial court said, “I overrule the objection.” The Commonwealth proceeded to ask Rivera details [73]*73about the shooting. Rivera corroborated the fact that Ruben hit Santos with the stick after Santos punched Omar in the face. Rivera also testified that Omar did not have a weapon, and Rivera did not see Omar hit anyone prior to the shooting. Rivera explained,
[Cortez-Hernandez] went up to the yard, and when he said that phrase, “que vale mierda,” he took out the gun and he pointed the gun, and it was some seconds—he took out the gun and he started to move around like this (indicating), and he said that it was no vale mierda, and he fired it. A few seconds went by, and he took it up again and he fired again.
Rivera responded, “no,” when asked whether anyone in Omar’s group had gotten into a physical fight with Cortez-Hernandez.
As the Commonwealth concluded its re-direct, defense counsel made some indication, the nature of which is unclear from the record, to which the court responded, “No.” Defense counsel then requested and received a bench conference in which the following discussion took place:
MS. IRVING [Defense counsel]: At the time that Ms. Millette started her direct examination, she never talked about the actual shooting. She only talked about when they were outside of Mike’s, walking, waiting until the Defendant and his friends had passed, and that’s where her cross—her direct ended.
THE COURT: Then you should have objected. I do not allow recross.
MS. IRVING: Judge, I did object. If I can—
THE COURT: You did object, and then she went in—you objected before it went into the shooting. After the shooting you did not object.
MS. IRVING: If I may just make my record clear, then. I objected when I thought she exceeded my scope. She mentioned that she could call him again, at which the point the Court—
THE COURT: Overruled your objection.
[74]*74MS. IRVING:—overruled the objection. And I was under the impression that instead of having her call him again one more time that she could continue going because I thought she had exceeded the scope.
THE COURT: No. I overruled the objection, you did not object again, so the objection is noted. You cannot go recross. Thank you. You may step back.
MS. IRVING: Please note my exception. Thank you, sir.
Following this exchange, Cortez-Hernandez’s attorney did not seek an additional opportunity to re-cross Rivera or otherwise proffer for the record the questions she would have asked Rivera or the expected answers.
Cortez-Hernandez later took the stand in his own defense. He testified that when he learned Omar and two friends were outside the restaurant, he got nervous so he called a friend to bring him a gun. After he left El Mexicano, he didn’t realize there was any trouble until Santos “passed me running ... holding his head----” At that point, Cortez-Hernandez turned around and saw one of Omar’s friends approaching him with a stick. He testified that he raised his hands for protection and the man hit his hands with the stick. Cortez-Hernandez then “ran behind a tree.”
Although Cortez-Hernandez’s group outnumbered Omar’s group nine to four, Cortez-Hernandez claimed eight people surrounded him, causing him to tremble with fear and feel like he could lose “my life right then and there.” He testified the group was only about five feet away from him. Cortez-Hernandez testified he pulled out his gun to scare Omar’s group off, but when they didn’t back off, he shot toward the ground. Two of the bullets hit Omar, even though Cortez-Hernandez maintained he never aimed at anyone. Cortez-Hernandez admitted Omar was not the individual who hit him that evening, nor did he ever see Omar with any weapons. After he fired the rounds, Cortez-Hernandez did not stop to see whether he had hit anyone. Instead, he fled the scene and stashed the weapon at a friend’s residence nearby.
[75]*75At the conclusion of the evidence, Cortez-Hernandez proffered model jury instructions on excusable self-defense and voluntary manslaughter. The trial court refused both instructions finding they were inapplicable to the facts presented at trial. Instead, the court instructed the jury on justifiable self-defense, and first and second-degree murder.
The jury found Cortez-Hernandez guilty of both first-degree murder and use of a firearm during the commission of a felony, and fixed his sentence at 63 years imprisonment. The trial court entered final judgment on March 9, 2010. Cortez-Hernandez noted this appeal.
II Analysis
A. Trial Court’s Refusal to Allow Re-Cross-Examination
Cortez-Hernandez first contends the trial court erred in refusing to allow him the right to re-cross-examine a prosecution witness, Hermenjildo Rivera, after the Commonwealth brought out new information on re-direct. Cortez-Hernandez specifically alleges the trial court erred in not allowing him re-cross-examination concerning matters brought out for the first time on Rivera’s re-direct by the prosecutor. The Commonwealth agrees the trial court erred in refusing to allow re-cross-examination of Rivera, but asserts the error is “not reversible error” because Cortez-Hernandez failed to proffer the questions he would have asked Rivera on re-cross and the expected answers. We do not address the merits of this assignment of error because it is not properly preserved for appeal.
Rule 5A:18 provided that “[n]o ruling of the trial court ... will be considered as a basis for reversal unless the objection was stated together with the grounds therefor at the time of the ruling.”2 The rule requires that “[i]n order to [76]*76preserve an issue for appeal, ‘an objection must be timely made and the grounds stated with specificity.’ ” McDuffie v. Commonwealth, 49 Va.App. 170, 177, 638 S.E.2d 139, 142 (2006) (quoting Marlowe v. Commonwealth, 2 Va.App. 619, 621, 347 S.E.2d 167, 168 (1986)). “To be timely, an objection must be made when the occasion arises—at the time the evidence is offered or the statement made.” Marlowe, 2 Va.App. at 621, 347 S.E.2d at 168 (citation omitted). “The purpose of the rule is to ensure that any perceived error by the trial court is ‘promptly brought to the attention of the trial court with sufficient specificity that the alleged error can be dealt with and timely addressed and corrected when necessary.’ ” Wood v. Commonwealth, 57 Va.App. 286, 303, 701 S.E.2d 810, 818 (2010) (quoting Brown v. Commonwealth, 8 Va.App. 126, 131, 380 S.E.2d 8, 10 (1989)). “If a party fails to timely and specifically object, she waives her argument on appeal.” Id. (citing Arrington v. Commonwealth, 53 Va.App. 635, 641, 674 S.E.2d 554, 557 (2009)).
Moreover, “[i]n Virginia, when ‘testimony is rejected before it is delivered, an appellate court has no basis for adjudication unless the record reflects a proper proffer.’ ” Ray v. Commonwealth, 55 Va.App. 647, 649, 688 S.E.2d 879, 880 (2010) (quoting Whittaker v. Commonwealth, 217 Va. 966, 968, 234 S.E.2d 79, 81 (1977)). “ ‘When an appellant claims a trial court abused its discretion in excluding evidence, we cannot competently determine error—much less reversible error— without a proper showing of what that testimony would have been.’ ” Id. (quoting Tynes v. Commonwealth, 49 Va.App. 17, 21, 635 S.E.2d 688, 689 (2006)). “Though sometimes thought of as a mere waiver principle, the proffer requirement serves the higher purpose of safeguarding our duty under Code § 8.01-6783 to reverse only when the trial court error actually [77]*77prejudiced the defense.” Id. at 650, 688 S.E.2d at 881 (citing Kirby v. Commonwealth, 50 Va.App. 691, 698-99, 653 S.E.2d 600, 603-04 (2007)). Thus,
Absent a proffer showing harm was done, we are forbidden to consider the question----This is because a proffer allows us to examine both the admissibility of the proposed testimony, and whether, even if admissible, its exclusion prejudiced the proffering party.... We can perform this examination only when the proponent proffers the testimony he expected to elicit, rather than merely his theory of the case.
Id. (quotations and citatiohs omitted). Indeed, “even when Ve are not totally in the dark concerning the nature of the evidence,’ we still must ‘know enough about the specifics’ to be able to ‘say with assurance’ that the lower court committed prejudicial error.” Tynes, 49 Va.App. at 22, 635 S.E.2d at 690 (quoting Smith v. Hylton, 14 Va.App. 354, 358, 416 S.E.2d 712, 715 (1992)).
As the Commonwealth correctly notes, these general principles apply to testimony excluded on cross-examination. See, e.g., Spencer v. Commonwealth, 238 Va. 295, 305, 384 S.E.2d 785, 792 (1989) (“Spencer contends that the trial court limited his cross-examination of Dr. Roberts on this point. Because Spencer failed to proffer the questions he wanted to ask Dr. Roberts and the answers Dr. Roberts would have made, we are unable to review Spencer’s claim.”); Clagett v. Commonwealth, 252 Va. 79, 95, 472 S.E.2d 263, 272 (1996) (“The trial court sustained the Commonwealth’s objection to Clagett’s attempt to cross-examine the lead investigator concerning Holsinger’s remorse for her part in the crime. As Clagett failed to proffer the testimony he expected to elicit, we will not consider this issue on appeal.”). In such cases, as long as the trial court does not prohibit counsel from proffering the necessary evidence for the record, we will not disturb the [78]*78court’s ruling on appeal. See Williams v. Harrison, 255 Va. 272, 277, 497 S.E.2d 467, 471 (1998) (“Williams did not proffer the additional questions he intended to ask or the additional testimony he expected to elicit from further cross-examination, nor was he prevented from doing so by the trial court ... [i]n the absence of a proffer, we will not consider this issue on appeal.” (emphasis added) (citation omitted)).
In this case, the Commonwealth called Rivera to the stand and questioned him about some of the events leading up to the May 31, 2008 shooting of Omar. The Commonwealth did not ask Rivera on direct examination' about the shooting itself. During cross-examination, counsel for Cortez-Hernandez also did not ask Rivera about the shooting. Nevertheless, during re-direct examination, the Commonwealth asked Rivera about the fight and the shooting. Cortez-Hernandez’s counsel objected, arguing only that the Commonwealth exceeded the scope of direct and cross. When the Commonwealth offered to “reheve [Rivera] and re-call him back,” the trial court, without further comment, overruled the objection. Upon the conclusion of re-direct, the trial court precluded Cortez-Hernandez’s counsel from further cross-examination of the witness. Although counsel again noted her objection, she did not proffer the questions she would have asked or Rivera’s expected answers for the record.
Assuming the trial court erred procedurally in disallowing re-cross on matters brought out for the first time on re-direct, as the Commonwealth suggests, we hold that in light of Cortez-Hernandez’s failure to proffer the evidence he expected to obtain, we cannot ascertain whether the asserted error is reversible.4 Cortez-Hernandez failed to proffer his questions and Rivera’s expected answers for the record, and the record fails to demonstrate that the trial court prohibited [79]*79Cortez-Hernandez from doing so. Cortez-Hernandez also failed to re-call the witness to obtain any desired testimony during his own case-in-chief, as he could have done. Without a proper proffer, and because Cortez-Hernandez did not call the witness to testify during his own case, we cannot “competently” ascertain whether or not the trial court’s refusal to allow counsel to re-cross-examine Rivera was error, “much less reversible error.” Ray, 55 Va.App. at 649, 688 S.E.2d at 880.5
Moreover, contrary to the assertion of the dissent, there is no constitutional dimension to the asserted error properly before us, as Cortez-Hernandez never objected to the trial court’s refusal to allow re-cross-examination of Rivera on the specific basis that his constitutional right to confrontation required it.6 Indeed, Cortez-Hernandez never mentioned the Sixth Amendment at all. Rather, his only stated objection to the Commonwealth’s questions was that they “exceeded the scope of direct and cross.” The trial court was, therefore, never afforded the opportunity to correct any alleged constitutional error. It follows that because Cortez-Hernandez did not raise an objection based on his right of confrontation, that specific objection is not properly preserved for appeal and we [80]*80will not consider it. See West Alexandria Prop., Inc. v. First Virginia Mortgage and Real Estate Inv. Trust, 221 Va. 134, 138, 267 S.E.2d 149, 151 (1980) (“On appeal, though taking the same general position as in the trial court, an appellant may not rely on reasons which could have been but were not raised for the benefit of the lower court.”); Edwards v. Commonwealth, 41 Va.App. 752, 760, 589 S.E.2d 444, 448 (2003) (en banc) (“Making one specific argument on an issue does not preserve a separate legal point on the same issue for review.”).7
In sum, because Cortez-Hernandez failed to proffer the questions he would have asked and Rivera’s expected answers to those questions for the record, and because he did not specifically raise an objection to the court’s decision based upon the Sixth Amendment right to confrontation, we find the issue is not properly preserved for appeal and we, thus, affirm the trial court as to this assignment of error.
B. Trial Court’s Refusal to Grant Jury Instructions on Excusable Self-Defense and Voluntary Manslaughter
Cortez-Hernandez also claims the trial court erred in refusing to grant his proposed jury instructions on excusable self-defense and voluntary manslaughter. We disagree.
“ ‘On appeal, when the issue is a refused jury instruction, we view the evidence in the light most favorable to [81]*81the proponent of the instruction.’ ” Connell v. Commonwealth, 34 Va.App. 429, 436, 542 S.E.2d 49, 53 (2001) (quoting Lynn v. Commonwealth, 27 Va.App. 336, 344, 499 S.E.2d 1, 4-5 (1998)). Nevertheless, “the trial court should instruct the jury only on those theories of the case which find support in the evidence.” Morse v. Commonwealth, 17 Va.App. 627, 632, 440 S.E.2d 145, 149 (1994). Indeed, “[i]t is a fundamental principle that ‘although an instruction may correctly state the law, it should not be given if it is inapplicable to the facts in evidence ... [and] might confuse or distract the jury.’ ” Id. at 633, 440 S.E.2d at 149 (quoting King v. Commonwealth, 2 Va.App. 708, 711, 347 S.E.2d 530, 531 (1986)).
Excusable homicide in self-defense occurs where the accused, although in some fault in the first instance in provoking or bringing on the difficulty, when attacked retreats as far as possible, announces his desire for peace, and kills his adversary from a reasonably apparent necessity to preserve his own life or save himself from great bodily harm.
Bailey v. Commonwealth, 200 Va. 92, 96, 104 S.E.2d 28, 31 (1958) (emphases added). On the other hand, “fjJustifiable homicide in self-defense occurs where a person, vnthout any fault on his part in provoking or bringing on the difficulty, kills another under reasonable apprehension of death or great bodily harm to himself.” Id. (emphasis added). In considering a defendant’s assertion of self-defense, we recognize the “well-established principle that one assaulted may use only such force as appears to him reasonably necessary to repel the attack.” Cook v. Commonwealth, 219 Va. 769, 773, 250 S.E.2d 361, 364 (1979).
In this case, the trial court rejected Cortez-Hernandez’s proposed jury instruction on excusable self-defense because “there is [obviously] no evidence on both sides to back up [the instruction].” The trial court noted that even under Cortez-Hernandez’s own version of events, he was “completely without fault” in the altercation. In fact, Cortez-Hernandez requested and received a jury instruction on justifiable self-defense, which provided that he “was without fault in provok[82]*82ing or bringing on the fight or difficulty.” Concluding there was “no evidence of either side that there was some degree of fault [on the part of Cortez-Hernandez],” the instruction on excusable self-defense was refused. The trial court’s ruling is not plainly wrong, even viewed from the standpoint of the proponent of the instruction.
In fact, even if Cortez-Hernandez was at fault in the altercation, the record fails to prove he retreated as far as he safely could under the circumstances, that he attempted to abandon the fight, that he made known his desire for peace, and that he reasonably feared great bodily harm to himself. Cortez-Hernandez was the only individual in the entire group armed with a firearm, and he concedes Omar never hit or threatened anyone or otherwise carried a weapon himself. Significantly, Omar’s blood was found 15 feet from where Cortez-Hernandez stood, wielding his gun. Cortez-Hernandez also testified that the source of his “fear” was an altercation that took place in 2002 that did not involve Omar’s group in any way. He also stated he was surrounded by eight people, when Omar’s group only included four. Despite the fact that no one in Omar’s group spoke to or threatened him, Cortez-Hernandez fired his gun toward the small group, only one of whom was himself “armed” with a mere stick. Moreover, rather than expressing a desire for peace, Cortez-Hernandez yelled out “Que vale mierdas,” a Mexican idiomatic expression meaning something along the lines of “Who’s the next motherfucker?” or “to not be worth shit,” or “I’m going to finish you up.”
We can only conclude on these facts that the trial court did not err in refusing to grant Cortez-Hernandez’s proposed jury instruction on excusable self-defense. As the trial court found, the evidence failed to support the instruction.
With respect to voluntary manslaughter, it is well settled that if a jury in a first-degree murder case rejects an instruction on the lesser-included offense of second-degree murder and finds the defendant guilty of first-degree murder, then it “necessarily rejected the factual basis upon which it [83]*83might have rendered a verdict on the lesser-included offense of voluntary manslaughter.” Turner v. Commonwealth, 23 Va.App. 270, 278, 476 S.E.2d 504, 508 (1996), aff'd, 255 Va. 1, 492 S.E.2d 447 (1997). In such cases, any alleged error in the trial court’s refusal to grant an instruction on voluntary manslaughter would be harmless. Id.
Here, as in Turner, the jury rejected the instruction on second-degree murder and convicted Cortez-Hernandez of first-degree murder. It follows that, as in Turner, the jury “would never have reached a voluntary manslaughter verdict.” Any supposed error in refusing to award an instruction on voluntary manslaughter would, therefore, be harmless. For that reason, we affirm the trial court’s refusal to award a voluntary manslaughter instruction.
III. Conclusion
For the foregoing reasons, we do not consider Cortez-Hernandez’s first assignment of error, because he failed to properly preserve it for appeal. However, we affirm the trial court’s refusal to award a jury instruction on excusable self-defense, since the evidence failed to support such an instruction. We also find the trial court did not err in refusing an instruction on voluntary manslaughter, because the jury necessarily rejected the factual premise upon which to convict Cortez-Hernandez of that offense when it convicted him of first-degree murder.
Affirmed.
