1 Samuel 29:8

David said, But what have I done? This was deep dissimulation and flattery in David, no way to be justified. But who, that has not experienced it, can know how strong a temptation they who attend on great men are under to compliment them and dissemble. David, no doubt, heartily rejoiced at this dismission; but as he did not know how much longer he might be obliged to stay in the land of the Philistines, he seems to have yielded to a temptation that prudence required him to carry it fair toward them, and to pretend to have that concern upon this occasion which he certainly did not feel.
