A naughty person, a wicked man, walketh with a froward mouth. A naughty person - אדם בליעל adam beliyal, "Adam good for nothing." When he lost his innocence. A man apostata; Old MS. Bible.
A wicked man - איש און ish aven. He soon became a general transgressor after having departed from his God. All his posterity, unless restored by Divine grace, are men of Belial, and sinners by trade; and most of them, in one form or other, answer the character here given. They yield their members instruments of unrighteousness unto sin.
