Solomon
Proverbs 17:20BSB·traditional attribution

The one with a perverse heart finds no good, and he whose tongue is deceitful falls into trouble.

Matthew Henry Presbyterian

Note, 1. Framing ill designs will be of no advantage to us; there is nothing got by them: He that has a froward heart, that sows discord and is full of resentment, cannot promise himself to get by it sufficient to counterbalance the loss of his repose and reputation, nor can he take any rational satisfaction in it; he finds no good. 2.

John Gill Reformed Baptist

He that hath a froward heart findeth no good,.... Who is of a perverse spirit, meditates and devises evil things; is not ingenuous and sincere, but false and deceitful to God and men: such an one gets no good from either; he obtains not the favour of God, nor a good name, credit, and reputation among men; and he that hath a perverse tongue falleth...

Jamieson-Fausset-Brown Reformed

The second clause advances on the first. The ill-natured fail of good, and the cavilling and fault-finding incur evil.
