Isaiah 38:3

Then he said, “While the child was still alive, I fasted and wept; for I said, ‘Who knows, Yahweh may be gracious to me, that the child may live.’

Now in the fourteenth year of King Hezekiah, Sennacherib king of Assyria came up against all the fortified cities of Judah and seized them.

In those days Hezekiah became ill to the point of death. And Isaiah the prophet the son of Amoz came to him and said to him, “Thus says Yahweh, ‘Set your house in order, for you shall die and not live.’”

In those days Hezekiah became sick to the point of death; and he prayed to Yahweh, and Yahweh spoke to him and gave him a miraculous sign.

And the king of Assyria sent Rabshakeh from Lachish to Jerusalem to King Hezekiah with a heavy military force. And he stood by the conduit of the upper pool on the highway of the fuller’s field.
