Proverbs 16:32
The same idea in other traditions

Hold to forgiveness; command what is right; But turn away from the ignorant.
Not to commit any sin, to do good, and to purify one's mind, that is the teaching of (all) the Awakened.

(A man) should elevate his self by his self; he should not debase his self, for even (a man's) own self is his friend, (a man's) own self is also his enemy. To him who has subjugated his self by his self, his self is a friend; but to him who has not restrained his self, his own self behaves inimically, like an enemy.
