2 Kings 20:7-9

20:7 Isaiah ordered, “Get a fig cake.” So they did as he ordered and placed it on the ulcerated sore, and he recovered.

20:8 Hezekiah had said to Isaiah, “What is the confirming sign that the Lord will heal me and that I will go up to the Lord’s temple the day after tomorrow?” 20:9 Isaiah replied, “This is your sign from the Lord confirming that the Lord will do what he has said. Do you want the shadow to move ahead ten steps or to go back ten steps?”
