Isaiah 53:4
2 He sprouted up like a twig before God, like a root out of parched soil; he had no stately form or majesty that might catch our attention, no special appearance that we should want to follow him. 3 He was despised and rejected by people, one who experienced pain and was acquainted with illness; people hid their faces from him; he was despised, and we considered him insignificant. 4 But he lifted up our illnesses, he carried our pain; even though we thought he was being punished, attacked by God, and afflicted for something he had done. 5 He was wounded because of our rebellious deeds, crushed because of our sins; he endured punishment that made us well; because of his wounds we have been healed.
LXX Isaiah 53:4
2 He grew up before him like a child, like a root in a thirsty land; he has no form or glory, and we saw him, and he had no form or beauty. 3 But his form was without honor, failing beyond all men, a man being in calamity and knowing how to bear sickness; because his face is turned away, he was dishonored and not esteemed. 4 This one bears our sins and suffers pain for us, and we accounted him to be in trouble and calamity and ill-treatment. 5 But he was wounded because of our acts of lawlessness and has been weakened because of our sins; upon him was the disciplined of our peace; by his bruise we were healed.
Notes and References
"... The LXX of Isaiah 53:4 differs considerably from Matthew 8:17. Unlike Matthew 8:17 and the Hebrew texts, the LXX does not refer to sicknesses. Instead, the LXX mentions ἁμαρτίας (“sins”). Matthew 8:17 does not include the rest of Isaiah 53:4, either. Thus, Matthew 8:17 is more similar to Isaiah 53:4 in the Hebrew texts than it is to the LXX. The introductory formula in Matthew 8:17 and terminology shared between Matthew 8:17 and the Hebrew versions of Isaiah 53:4 indicate that Matthew quotes Isaiah 53:4 ..."
