Solomon
Proverbs 13:5ESV·traditional attribution

The righteous hates falsehood, but the wicked brings shame and disgrace.

Matthew Henry Presbyterian @wholebiblehenry

Note, 1. Where grace reigns sin is loathsome. It is the undoubted character of every righteous man that he hates lying (that is, all sin, for every sin is a lie, and particularly all fraud and falsehood in commerce and conversation), not only that he will not tell a lie, but he abhors lying, from a rooted reigning principle of love to truth and justice, and conformity to God. 2.

John Gill Reformed Baptist @doctorgill

A righteous man hateth lying,.... Or, "a word of falsehood" (y); as being contrary to honour, truth, and conscience. He hates it in himself and others; he hates all sorts of lies, lies in common conversation, religious lies, doctrinal ones, false doctrines, lies spoken in hypocrisy; such as the followers of antichrist spread, being given up unto them that they might be damned, Ti1 4:2...

Jamieson-Fausset-Brown Reformed @jfbcommentary

loathsome . . . shame--better, causeth shame and reproach (compare Pro 19:26), by slander, &c., which the righteous hates.
