Isaiah 38:5

2 And Hezekiah, turning his face to the wall, made his prayer to the Lord, saying,

3 O Lord, keep in mind how I have been true to you with all my heart, and have done what is good in your eyes. And Hezekiah gave way to bitter weeping.

4 Then the word of the Lord came to Isaiah, saying,

5 Go to Hezekiah, and say, The Lord, the God of David, your father, says, Your prayer has come to my ears, and I have seen your weeping: see, I will give you fifteen more years of life.

6 And I will keep you and this town safe from the hands of the king of Assyria: and I will keep watch over this town.

7 And Isaiah said, This is the sign the Lord will give you, that he will do what he has said:

8 See, I will make the shade which has gone down on the steps of Ahaz with the sun, go back ten steps. So the shade went back the ten steps by which it had gone down.
