'Set Your House in Order' in the Bible

In those days [when Sennacherib first invaded Judah] Hezekiah became deathly ill. The prophet Isaiah the son of Amoz came and said to him, “Thus says the Lord, ‘Set your house in order, for you shall die and not recover.’”

In those days Hezekiah [king of Judah] became sick and was at the point of death. And Isaiah the prophet, the son of Amoz, came to him and said, “For the Lord says this, ‘Set your house in order and prepare a will, for you shall die; you will not live.’”
