1 Samuel 24:7

So David restrained his men with these words, and did not allow them to rise against Saul. And 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, (yea, I have delivered him without cause who was my adversary),

and blessed be thy discretion, and blessed be thou, who have kept me this day from blood guiltiness, and from avenging myself with my own hand.

But I say to you, love your enemies, bless those who curse you, do good to those who hate you, and pray for those who mistreat you and persecute you,

rendering to no man evil for evil, premeditating things right 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, (yea, I have delivered him without cause who was my adversary),

But I say to you, love your enemies, bless those who curse you, do good to those who hate you, and pray for those who mistreat you and persecute you,

rendering to no man evil for evil, premeditating things right in the sight of all men.

and blessed be thy discretion, and blessed be thou, who have kept me this day from blood guiltiness, and from avenging myself with my own hand.
