8 And Hezekiah said to Isaiah, What is to be the sign that the Lord will make me well, and that I will go up to the house of the Lord on the third day?
9 And Isaiah said, This is the sign the Lord will give you, that he will do what he has said; will the shade go forward ten degrees or back?
10 And Hezekiah said in answer, It is a simple thing for the shade to go forward; but let it go back ten degrees.
11 Then Isaiah the prophet made prayer to the Lord, and he made the shade go back ten degrees from its position on the steps of Ahaz.
12 At that time, Merodach-baladan, the son of Baladan, king of Babylon, sent letters with an offering to Hezekiah, because he had news that Hezekiah had been ill.
