New King James Version

⁷ Then ^(A)Isaiah said, “Take a lump of figs.” So they took and laid it on the boil, and he recovered.

⁸ And Hezekiah said to Isaiah, ^(B)“What is the sign that the Lord will heal me, and that I shall go up to the house of the Lord the third day?”

⁹ Then Isaiah said, ^(C)“This is the sign to you from the Lord, that the Lord will do the thing which He has spoken: shall the shadow go forward ten degrees or go backward ten degrees?”
