Isaiah 53:4-5, 11

Yet it was our weaknesses he carried; it was our sorrows that weighed him down. And we thought his troubles were a punishment from God, a punishment for his own sins! But he was pierced for our rebellion, crushed for our sins. He was beaten so we could be whole. He was whipped so we could be healed.

When he sees all that is accomplished by his anguish, he will be satisfied. And because of his experience, my righteous servant will make it possible for many to be counted righteous, for he will bear all their sins.
