Isaiah 38:17-22

17 Surely it was for my welfare that I had great bitterness; but you have held back my life from the pit of destruction, for you have cast all my sins behind your back.
18 For Sheol cannot thank you, death cannot praise you; those who go down to the Pit cannot hope for your faithfulness.
19 The living, the living, they thank you, as I do this day; fathers make known to children your faithfulness.
20 The Lord will save me, and we will sing to stringed instruments all the days of our lives, at the house of the Lord.
21 Now Isaiah had said, "Let them take a lump of figs, and apply it to the boil, so that he may recover."
22 Hezekiah also had said, "What is the sign that I shall go up to the house of the Lord?"
