Proverbs 17:12-14

Amplified Bible

¹² 
Let a man meet a [ferocious] bear robbed of her cubs
Rather than the [angry, narcissistic] fool in his folly.^(A)
13 
Whoever returns evil for good,
Evil will not depart from his house.^(B)
14 
The beginning of strife is like letting out water [as from a small break in a dam; first it trickles and then it gushes];
Therefore ^[a]abandon the quarrel before it breaks out and tempers explode.
