Psalms 7:5

That repaid. This seems better than "my peaceable one," as some translate the Hebrew, for it would be but a small commendation not to injure a friend: the pagans do as much. Duport therefore agrees with the Vulgate, and St. Jerome has, "If I have rendered evil to those who did me any, and sent my enemies empty away;" or, as the Hebrew is in the future, "I will let my enemies depart without fighting;" which is equivalent to, I will gain no advantage over them. (Berthier) --- The man who takes revenge, injures himself, and becomes the devil's slave. (St. Augustine) --- David had been so far from giving way to ingratitude, that he would not even hurt his enemy. (Haydock) --- He let Saul escape, when he might easily have slain him. [1 Samuel xxvi.] (Calmet)
