1 Samuel 24:7

So David strongly rebuked his men with these words and did not let them rise up against Saul. Saul got up, left the cave and went on his way.

If I have done evil to him who was at peace with me,
Or without cause robbed him who was my enemy,

And blessed be your discretion and discernment, and blessed be you, who has kept me from bloodshed this day and from avenging myself by my own hand.

But I say to you, love [that is, unselfishly seek the best or higher good for] your enemies and pray for those who persecute you,

Never repay anyone evil for evil. Take thought for what is right and gracious and proper in the sight of everyone.

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 done evil to him who was at peace with me,
Or without cause robbed him who was my enemy,

But I say to you, love [that is, unselfishly seek the best or higher good for] your enemies and pray for those who persecute you,

Never repay anyone evil for evil. Take thought for what is right and gracious and proper in the sight of everyone.

And blessed be your discretion and discernment, and blessed be you, who has kept me from bloodshed this day and from avenging myself by my own hand.
