He deviseth mischief upon his bed; rather, he deviseth iniquity—the same word as in the preceding verse. In the night, when he should be looked in innocent slumber, he lies awake, devising wicked schemes against others (comp.
Proverbs 4:16; Micah 2:1). He setteth himself in a way that is not good. More correct than the Prayer-book Version, "He hath set himself in no good way." The wicked man is not merely negatively bad; he determinately chooses a path of life that is evil.
He abhorroth not evil. He has no aversion to it, no horror of it, no shrinking from it. Whether a thing is right or wrong is to him a matter of complete indifference. So callous is he, so hardened.
