John Gill

Thou lovest evil more than good,.... Indeed not good at all; such comparatives being strong negatives; see Psa 118:8; a wicked man loves evil, and nothing else; his carnal mind being enmity to all that is good and lying rather than to speak righteousness; as appears by his affirming that Ahimelech inquired of the Lord for David, when he did not, Sa1 22:10; and by suffering some things to pass for truths which were falsehoods, when it lay in his power to have disproved them: and such a lover of lies is antichrist; see Ti1 4:2. Selah; on this word; see Gill on Psa 3:2. The Targum renders the word "Selah" here "for ever", as in Psa 52:5.
