Commentaries:
Jamieson, Fausset, and Brown
A naughty person—literally, "A man of Belial," or of worthlessness, that is, for good, and so depraved, or wicked (compare I Samuel 25:25; I Samuel 30:22, etc.). Idleness and vice are allied. Though indolent in acts, he actively and habitually (walketh) is ill-natured in speech (Proverbs 4:24).
