Proverbs 24:7-9

Wycliffe Bible

⁷ Wisdom is high to a fool; in the gate he shall not open his mouth. (Wisdom is too high for a fool to reach; in court/at the city gates, he shall not even dare to open his mouth.)

⁸ He that thinketh to do evils, shall be called a fool.

⁹ The thought of a fool is (a) sin; and a backbiter is abomination of men (and a backbiter is an abomination to everyone).
