381 In those days Hezekiah became sick and was at the point of death. The prophet Isaiah son of Amoz came to him, and said to him, "Thus says the Lord: Set your house in order, for you shall die; you shall not recover." 2 Then Hezekiah turned his face to the wall, and prayed to the Lord: 3 "Remember now, O Lord, I implore you, how I have walked before you in faithfulness with a whole heart, and have done what is good in your sight." And Hezekiah wept bitterly. 4 Then the word of the Lord came to Isaiah: 5 "Go and say to Hezekiah, Thus says the Lord, the God of your ancestor David: I have heard your prayer, I have seen your tears; I will add fifteen years to your life. 6 I will deliver you and this city out of the hand of the king of Assyria, and defend this city. 7 "This is the sign to you from the Lord, that the Lord will do this thing that he has promised: 8 See, I will make the shadow cast by the declining sun on the dial of Ahaz turn back ten steps." So the sun turned back on the dial the ten steps by which it had declined.

When we pray in our sickness, though God send not to us such an answer as he here sent to Hezekiah, yet, if by his Spirit he bids us be of good cheer, assures us that our sins are forgiven, and that, whether we live or die, we shall be his, we do not pray in vain. See 2 Kings 20:1-11.
