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 Pro 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, Rev 2:24; feet that be swift in running to mischief; to commit all manner of sin with greediness, especially murder; see Pro 1:16. (e) "cogitationes iniquitatis", Montanus; "cogitationes vanitatis", Cocceius.
