Proverbs 17:4

A wicked doer giveth heed to false lips; and a liar giveth ear to a naughty tongue.

A wicked doer giveth heed to false lips,.... A man of an ill spirit, of a mischievous disposition, that delights in doing wickedness; he carefully attends to such as speak falsehood; he listens to lies and calumnies, loves to hear ill reports of persons, and takes pleasure in spreading them to the hurt of their characters; and men of bad hearts and lives give heed to seducing spirits, to false teachers, to inch as speak lies in hypocrisy, who sooth and harden them in their wickedness;

and a liar giveth ear to a naughty tongue: or, "to a tongue of destruction" {a}; a culumniating, backbiting tongue, which destroys the good name and reputation of men; and he that is given to lying is made up of lying, or is a lie itself, as the word signifies; who roves and makes a lie, as antichrist and his followers; such an one hearkens diligently to everything that may detract from the character of those especially he bears an ill will to: or it may be better rendered, "he that hearkens to a lie gives heed to a naughty tongue" {b}; for a lying tongue is a naughty one, evil in itself, pernicious in its effects and consequences.
