'Sick' in the Bible

Why should you be stricken and punished again [since no change results from it]?You [only] continue to rebel.The whole head is sickAnd the whole heart is faint and sick.

The Lord will consume the glory of Assyria’s forest and of its fruitful garden, both soul and body,And it will be as when a sick man wastes away.

And no inhabitant [of Zion] will say, “I am sick”;The people who dwell there will be forgiven their wickedness [their sin, their injustice, their wrongdoing].

This is the writing of Hezekiah king of Judah after he had been sick and had recovered from his illness:

At that time Merodach-baladan son of Baladan, king of Babylon, sent [messengers with] letters and a present to Hezekiah, for he had heard that he had been sick and had recovered.

Yet the Lord was willingTo crush Him, causing Him to suffer;If He would give Himself as a guilt offering [an atonement for sin],He shall see His [spiritual] offspring,He shall prolong His days,And the will (good pleasure) of the Lord shall succeed and prosper in His hand.
