He shall reward evil unto mine enemies: cut them off in thy truth.
He shall reward evil unto mine enemies. So the Qeri' reads х yaashiyb (H7725)]; but the Khethibh reads better, 'the evil shall return х yaashuwb (H7725)] unto mine enemies' (Psalms 7:16). 'The evil' is that which the Psalmist's adversaries wished to inflict. "Mine enemies" ( shorªraay (H8324)) - literally, those who watch me; insidious liers in wait for my halting (Psalms 5:8, note).
Cut them off in thy truth. The imperative expresses the certainty, and carries with it the operative power of the Word of God, which works by its own intrinsic efficacy. The truth of God ensures the destruction of the wicked, as necessary both for the fulfillment of God's promise to save the righteous, and for the vindication of God's justice in repaying wickedness at last, though He, in long-suffering, give a lengthened time for repentance.
