Proverbs 17:15

¹³ Whoso rewardeth evil for good, evil shall not depart from his house.

¹⁴ The beginning of strife is as when one letteth out water: therefore leave off contention, before it be meddled with.

He that justifieth the wicked, and he that condemneth the just, even they both are abomination to the LORD.

¹⁶ Wherefore is there a price in the hand of a fool to get wisdom, seeing he hath no heart to it?

¹⁷ A friend loveth at all times, and a brother is born for adversity.
