Isaiah 38:1-8 New King James Version (NKJV)
Hezekiah’s Life Extended
38 In those days Hezekiah was sick and near death. And Isaiah the prophet, the son of Amoz, went to him and said to him, “Thus says the Lord: ‘Set your house in order, for you shall die and not live.’ ”
2 Then Hezekiah turned his face toward the wall, and prayed to the Lord, 3 and said, “Remember now, O Lord, I pray, how I have walked before You in truth and with a [a]loyal heart, and have done what is good in Your sight.” And Hezekiah wept bitterly.
4 And the word of the Lord came to Isaiah, saying, 5 “Go and tell Hezekiah, ‘Thus says the Lord, the God of David your father: “I have heard your prayer, I have seen your tears; surely I will add to your days fifteen years. 6 I will deliver you and this city from the hand of the king of Assyria, and I will defend this city.” ’ 7 And this is the sign to you from the Lord, that the Lord will do this thing which He has spoken: 8 Behold, I will bring the shadow on the sundial, which has gone down with the sun on the sundial of Ahaz, ten degrees backward.” So the sun returned ten degrees on the dial by which it had gone down.
