Proverbs 6:12

a naughty person Lit. a man of Belial. The Heb. word Belialmeans, "of no profit," "worthless," and, according to the Heb. idiom, a man of, or a son of (Deuteronomy 13:13) Belial, is an unprofitable or worthless person. Here, however, the word "Belial" is in apposition with "man," "a man (who is) worthless, a good-for-nothing fellow." The word appears to have been personified by the later Jews, and is used in the form Belial, or Beliar, to denote Satan (2 Corinthians 6:15, where see note in this Series).

walketh The R.V., following the Heb. pointing, is more abrupt and forcible:

A worthless person, a man of iniquity;

He walketh with a froward mouth.
