The God of my mercy shall prevent me: God shall let me see my desire upon mine enemies.
The God of my mercy. So the Qeri' reads, but the Khethibh has 'My God shall prevent me with His mercy,'-literally, 'shall anticipate in giving me His grace' (Psalms 21:3). The Qeri' was copied from Psalms 59:17, end.
God shall let me see my desire upon mine enemies - (Psalms 54:7, end.)
