If your enemies are hungry, give them food to eat,
if thirsty, give something to drink;
For live coals you will heap on their heads,
and the LORD will vindicate you.
The north wind brings rain,
and a backbiting tongue, angry looks.
It is better to dwell in a corner of the housetop
than in a mansion with a quarrelsome wife.
Cool water to one faint from thirst
is good news from a far country.

Proverbs 25:21–28
