Proverbs 19:28 - Joseph Benson’s Commentary on the Old and New Testaments

An ungodly witness scorneth judgment Hath no reverence to the place of justice, nor to the presence of God there, nor to that sacred and solemn work, of executing judgment, but, in spite of all, gives in a false testimony. And the mouth of the wicked devoureth iniquity Uttereth it with as great greediness, delight, and ease, as they swallow down delicious meats and drinks; or, is as eager to commit it in word and deed, as if it were as necessary to their well-being as the food they eat.
