A naughty person, a wicked man,.... Or, "a man of Belial, a man of iniquity" (w). The former signifies an unprofitable man, a man good for nothing, that is of no use to God or man; or one that is lawless, that has thrown off the yoke of the law, and will not be subject to it; Belial is the name of the devil; and here it may design such as are his children, and will do his lusts: the latter phrase signifies one that is wholly given up to work wickedness. The characters well agree with the the lawless one, the man of sin and son of perdition, antichrist, Th2 2:3. Who walketh with a froward mouth; speaking perverse things, things contrary to the light of nature and reason, to law and Gospel; uttering lies, and deceit, and blasphemies against God and man; to which he has used himself, and in which he continues, as the word "walketh" signifies: so antichrist has a mouth opened in blasphemies against God and his saints, Rev 13:5. (w) "homo Belijahal, vir iniquitatis", Montanus, Vatablus, Baynus, Michaelis.
