A naughty person - בליעל אדם adam beliyal, "Adam good for nothing." When he lost his innocence. A man apostata; Old MS. Bible.
A wicked man - און איש 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.
A naughty person - literally, “a man of Belial,” i. e., a worthless man (see the Deuteronomy 13:13 note). This is the portrait of the man who is not to be trusted, whose look and gestures warn against him all who can observe. His speech is tortuous and crafty; his wink tells the accomplice that the victim is already snared; his gestures with foot and hand are half in deceit, and half in mockery.
