And when David had made an end of speaking these words to Saul, Saul said: Is this thy voice, my son David? And Saul lifted up his voice, and wept.

“Not even this act of benevolence moved Saul, however. Again he gathered an army and again he set out in pursuit, until he was a second time apprehended by David in the cave where he more clearly revealed his own iniquity and made the virtue of David even more resplendent. Envy is the most savage form of hatred. Favors render those who are hostile to us for any other reason more tractable, but kind treatment shown to an envious and spiteful person only aggravates his dislike. The greater the favors he receives, the more displeased and vexed and ill-disposed he becomes.”

“And he said to David, thou art more righteous than I,.... By which it appears he thought himself righteous, though David was more so; the righteousness of David was so glaring, that his enemy himself being judge acknowledges it, but will not confess his own wickedness, having no true sense of sin, nor real sorrow for it: for thou hast rewarded me good; in times past, and now; heretofore in killing Goliath, fighting his battles for him against the Philistines, driving the evil spirit from him, by playing on the harp before him, and now by sparing his life, only cutting off the skirt of his garment, when he could with equal ease have cut off his head: whereas I have rewarded thee evil: in seeking to take away his life at various times, by casting a javelin at him more than once, sending messengers to kill him, and hunting after him from place to place, to take him and slay him.”

“Voice. He was at such a distance, as not to be able to distinguish his features. — Wept. The greatest reprobates may sometimes feel sentiments of compunction, so that we need not here doubt of Saul’s sincerity. (Calmet) — He might otherwise have turned upon David with his 3,000, and easily have seized his prey. (Haydock)”

The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
