And David said to Abisai: Kill him not: for who shall put forth his hand against the Lord’s anointed, and shall be guiltless?

“But what great and wonderful and Christian patience is to be found in David from whom Christ descended according to the flesh! David often had the opportunity to kill King Saul, his persecutor, who was eager to destroy him. Yet when Saul was subject to him and in his power, David preferred to save his life and did not retaliate on his enemy but, on the contrary, even avenged him when he was killed. In short, many prophets have been killed, many martyrs have been honored with glorious deaths, and all have attained their heavenly crowns through the merit of patience, for a crown for sorrow and suffering cannot be obtained unless patience in sorrow and suffering precede.”

“For the truth is not preached with swords or with darts, nor by means of soldiers, but by persuasion and counsel. But what persuasion is there where fear of the emperor prevails? Or what counsel is there, when he who withstands them receives at last banishment and death? Even David, although he was a king and had his enemy in his power, did not prevent the soldiers by an exercise of authority when they wished to kill his enemy, but, as the Scripture says, David persuaded his men by arguments, and did not allow them to rise up and put Saul to death. But [the devil], being without arguments of reason, forces all men by his power, that it may be shown to all that their wisdom is not according to God but merely human, and that they who favor the Arian doctrines have indeed no king but Caesar; for by his means it is that these enemies of Christ accomplish whatsoever they wish to do.”

“But this is marvelous not only for the fact that he grants life to the one who is doing everything against his life, but because David, although he had been anointed to the office of king and knew that he would not otherwise partake of that position unless Saul were out of the way, judged it better to suffer ill patiently in his private low estate than to enter upon the kingship by satisfying his anger against the one who had caused him grief.”

“And David said to Abishai, destroy him not,.... He laid his commands upon him not to hurt him: for who can stretch forth his hand against the Lord's anointed, and be guiltless? since Saul was king, and appointed to that office by the Lord, and was anointed by his order for it, and invested with it by him, his person was sacred, and not to be touched; nor could his life be taken away by any without being guilty of a very great crime indeed, which it might be justly expected the Lord would resent and punish.”

“Guiltless. Saul was still his king, how wicked soever, and this title rendered his person inviolable. The eastern nations are very seldom guilty of rebellion, or of murdering their kings; a thing of which we find so many examples in the Roman, English, and French histories. (Calmet) — A private man could not lay violent hands upon the king without a crime; and therefore David represses Abisai, and commits his cause to God, chap. xxiv. 13. (Menochius) — He will not permit any one to destroy the life of the king, though he was already anointed to succeed him. (Worthington)”
