David
Psalm 139:20ASV·superscription

For they speak against thee wickedly, And thine enemies take thy name in vain.

C.H. Spurgeon Reformed Baptist

Godless men turn their own tongues, the gift of their Maker, into weapons against Him, and this from pure malice, asking nothing and gaining nothing but the pleasure of blasphemy itself. How can He do other than slay them? How can we do other than cast them off entirely?

John Gill Reformed Baptist

Wicked men are haters of God, and good men must hate them as such, not the creature, but the work, not the person but the rebellion. This hatred springs from love for God; we grieve because they assault the Very One we cherish, and expose themselves to ruin.

Psa 139:19-21 And this God is by many not only not believed in and loved, but even hated and blasphemed! The poet now turns towards these enemies of God in profound vexation of spirit. The אם, which is conditional in Psa 139:8, here is an optative o si, as in Psa 81:9; Psa 95:7.
