1 Samuel 24:7

So David checked his men with these words, and did not allow them to rise against Saul. Saul rose up out of the cave, and went on his way.

if I have rewarded evil to him who was at peace with me (yes, if I have delivered him who without cause was my adversary),

Blessed is your discretion, and blessed are you, that have kept me this day from blood guiltiness, and from avenging myself with my own hand.

But I tell you, love your enemies, and pray for those who persecute you,

Repay no one evil for evil. Respect what is honorable in the sight of all men.

So David stayed his servants with these words, and suffered them not to rise against Saul. But Saul rose up out of the cave, and went on his way.

if I have rewarded evil to him who was at peace with me (yes, if I have delivered him who without cause was my adversary),

But I tell you, love your enemies, and pray for those who persecute you,

Repay no one evil for evil. Respect what is honorable in the sight of all men.

Blessed is your discretion, and blessed are you, that have kept me this day from blood guiltiness, and from avenging myself with my own hand.
