Commentary on Proverbs 6:14

• Matthew Henry (Presbyterian), Matthew Henry's Complete Commentary on Proverbs 6:12-19: Solomon here gives us, I. The characters of one that is mischievous to man and dangerous to be dealt with.

• John Gill (Reformed Baptist), Exposition of the Old and New Testaments on Proverbs 6:14: Therefore shall his calamity come suddenly,.... Unthought of and unexpected: he that deviseth mischief to others secretly shall have no warning of his own ruin, nor time and means of preventing it; the destruction of antichrist will be sudden, and of all wicked men at the coming of Christ, Th1 5:3; suddenly shall he be broken without remedy; or, "and there shall be no healing"...
• Jamieson-Fausset-Brown (Reformed), Commentary Critical and Explanatory on the Whole Bible on Proverbs 6:14: Frowardness--as in Pro 2:14. deviseth--literally, "constructs, as an artisan." mischief--evil to others. discord--especially litigation. Cunning is the talent of the weak and lazy.
• Keil & Delitzsch (Lutheran), Biblical Commentary on the Old Testament on Proverbs 6:12-15: Pro 6:12-15 There follows now a third brief series of instructions, which run to a conclusion with a deterring prospect similar to the foregoing. 12 A worthless man, a wicked man, Is he who practiseth falsehood with his mouth; 13 Who winketh with his eyes, scrapeth with his foot, Pointeth with his fingers. 14 Malice is in his heart, He deviseth evil at all times, He spreadeth strife.
