Isaiah 63:4 - Exposition

For the day of vengeance is in my heart . Translate , for a day of vengeance was in my heart (comp Isaiah 34:8 ; Isaiah 61:2 ). "A day" is time enough for God to take vengeance, to kill, and to destroy. He hastens over work that is necessary, but uncongenial. But he lengthens out the time of release and redemption for his loved ones. The "day of vengeance" ushers in the "year of redemption." Is come ; rather, was come. The Divine speaker goes back to the time preceding the actual punishment of the nations.
