1 Samuel 24:7

So David persuaded his men with these words and did not permit them to attack Saul. And Saul rose up and left the cave and went on his way.

if I have repaid my friend with evil or plundered my enemy without cause,

Blessed be your discretion, and blessed be you, who have kept me this day from bloodguilt and from avenging myself with my own hand!

But I say to you, Love your enemies and pray for those who persecute you,

Repay no one evil for evil, but give thought to do what is honorable in the sight of all.

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 repaid my friend with evil or plundered my enemy without cause,

But I say to you, Love your enemies and pray for those who persecute you,

Repay no one evil for evil, but give thought to do what is honorable in the sight of all.

Blessed be your discretion, and blessed be you, who have kept me this day from bloodguilt and from avenging myself with my own hand!
