| Geneva Study Bible A naughty person, {f} a wicked man, walketh with a froward mouth. (f) He shows to what inconvenience the idle persons and sluggards come, by calling them unthrifty, or the men of Belial, and slanderous. Jamieson-Fausset-Brown Bible Commentary 12. A naughty person-literally, "A man of Belial," or of worthlessness, that is, for good, and so depraved, or wicked (compare 1Sa 25:25; 30:22, &c.). Idleness and vice are allied. Though indolent in acts, he actively and habitually (walketh) is ill-natured in speech (Pr 4:24). Matthew Henry's Concise Commentary 6:12-19 If the slothful are to be condemned, who do nothing, much more those that do all the ill they can. Observe how such a man is described. He says and does every thing artfully, and with design. His ruin shall come without warning, and without relief. Here is a list of things hateful to God. Those sins are in a special manner provoking to God, which are hurtful to the comfort of human life. These things which God hates, we must hate in ourselves; it is nothing to hate them in others. Let us shun all such practices, and watch and pray against them; and avoid, with marked disapproval, all who are guilty of them, whatever may be their rank. |
