Isaiah 25:8

In the Old Testament the jaw of death is bitter, since it is said, "Strong death is all devouring." In the New Testament the jaw of death is sweet, for it has swallowed death, as the apostle says: "Death is swallowed up in victory! O death, where is your victory? O death, where is your sting?"

Stricken by the indecency of this act [the golden calf], Moses broke the tablets and shattered the head of the calf and beat it to powder in order to destroy all traces of impiety. The first tablets were broken so that the second ones might be repaired whereon, through the teaching of the gospel, faithlessness, now utterly destroyed, vanished. Thus Moses shattered that Egyptian pride and by the authority of the eternal law checked that loftiness overreaching itself. Therefore David says, "And the Lord will break the cedars of Lebanon, and shatter them like the calf of Lebanon. Thus the people swallowed all faithlessness and pride, so that impiety and haughtiness might not swallow them. For it is better that each person be master of his flesh and its vices, that it may not be said of him that all-powerful death has devoured him, but rather, "death is swallowed up in victory!"

For which reason the Apostle placed: "Death has been swallowed up in contention; where is your contention, death? Where is your sting, O death?" And explaining the power of the testimony, he said: "But the sting of death is sin, and the power of sin is the law; but thanks be to God, who has given us victory through our Lord Jesus Christ." Therefore, what he interpreted as the resurrection of the Lord, we cannot nor dare interpret differently. Death, hell, and the devil may be understood, who was killed by the death of Christ, about whom Isaiah also speaks: "Death has been swallowed up by victory" (Isaiah 25:8, LXX translation). And afterwards it follows: "The Lord hath taken away every tear from every face." Now, however, some understand that the two brothers who were separated by death, according to the history of that time, are Israel and Judah, so that what was then prefigured partly may now be felt in its entirety, and that with every human race Israel and Judah must be liberated and redeemed.
