For their feet run to evil,.... To the evil of sin, to commit robberies and murder, and all manner of iniquity; they are eager upon it, and in haste and swift to do it, Pr 6:18 ; being carried away with their inordinate affections, which are as feet to the soul; and drawn aside with their lusts, and pushed on by Satan, and, encouraged by one another, and so rush on headlong to the evil of punishment also; and which is a reason why their ways and paths should be abstained from, because they bring upon them swift destruction; it is to their own hurt they run, as Jarchi interprets it; though the first sense seems best to agree with what follows;and make haste to shed blood; the blood of innocent persons, in order to get their substance, to cover their iniquity and shame, and that no information may be given of them; this is mentioned as having something very horrible in it, in order to deter from joining with them.
