John Gill Commentary Psalms 52:3

"Thou lovest evil more than good, And lying rather than to speak righteousness. Selah" — Psalms 52:3 (ASV)

You love evil more than good
Indeed not good at all; such comparatives being strong negatives; see (Psalms 118:8Psalms 118:9) ; 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, (1 Samuel 22:10 1 Samuel 22:15) ; 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 (1 Timothy 4:2) (2 Thessalonians 2:11) .

Selah; on this word, (See Gill on Psalms 3:2). The Targum renders the word "Selah" here "for ever", as in (Psalms 52:5) .
