christmas and the puzzling servant

Isaiah 52:13-15

He Was Pierced for Our Transgressions

Behold, my servant shall act wisely;
    he shall be high and lifted up,
    and shall be exalted.
14 As many were astonished at you—
    his appearance was so marred, beyond human semblance,
    and his form beyond that of the children of mankind—
15 so shall he sprinkle many nations.
    Kings shall shut their mouths because of him,
for that which has not been told them they see,
    and that which they have not heard they understand.
