Their feet run to evil: this seems to be taken from Proverbs 1:16. See Poole on "Proverbs 1:16". He had spoken of their hands, lips, and heart, &c. before, and now of their feet, to show that they were wholly set upon mischief. Their thoughts, i.e. their heart and mind, is set upon doing wrong and injury; they not only do evil, but do it deliberately. You have the wicked described by this kind of working of their thoughts, Psalms 64:6; they meditate on little or nothing else. Wasting and destruction are in their paths; a metaphor put for the behaviours and carriages of men; in what way or work soever they are engaged, it all tends to ruin and destruction. A metaphor taken from an overspreading torrent, or sweeping plague, or beasts of prey, that tear and devour whatsoever comes in their way.
