Proverbs 17:14-16

Complete Jewish Bible

¹⁴ Starting a fight is like letting water through [a dike] —
    better stop the quarrel before it gets worse.

¹⁵ He who justifies the wicked and he who condemns the righteous —
    both alike are an abomination to Adonai.

¹⁶ Why would a fool wish to pay for wisdom
    when he has no desire to learn?
