An heart that deviseth wicked imaginations, (h) feet that be swift in running to mischief,
(h) Meaning, the raging affections, which carry a man away in such sort that he cannot tell what he does.
An heart that deviseth wicked imaginations,.... Or, "thoughts of wickedness" (e); which are framed and formed in the heart: and this being the source and fountain of all wickedness, is placed in the midst of these hateful and abominable things; See Gill on Proverbs 6:14; evil thoughts and designs, both against God and men, are intended, which are forged and fabricated in the wicked heart of man; and may respect the depths of Satan in the antichristian beast of Rome, Revelation 2:24;
feet that be swift in running to mischief; to commit all manner of sin with greediness, especially murder; see Proverbs 1:16.
(e) "cogitationes iniquitatis", Montanus; "cogitationes vanitatis", Cocceius.
The fourth characteristic is a deceitful heart. On חרשׁ, vid., Proverbs 6:14, Proverbs 3:29, and on אין, Proverbs 6:12. The fifth: feet running with haste to evil; לרעה as לרע in Isaiah 59:7, echoing the distich Proverbs 1:16, as here, 17b and 18b. The connection מהר לרוּץ, propere cucurrit (contrast אחר ל), is equivalent to רץ מהר.
Deviseth - He whose practice it is to contrive wickedness. Swift - Such as greedily execute their wicked designs.
