See that none render evil for evil unto any man; but ever follow that which is good, both among yourselves, and to all men.
Christianity first taught this. The British triad defines three classes: the man of the devil returns evil for good; the man of men returns good for good, evil for evil; the man of God returns good for evil (Romans 12:17; 1 Peter 3:9).
Unto any man - whether unto a Christian or a pagan, however great the provocation.
Follow - as a matter of earnest pursuit.
Good - that which is for the good of others.
