2 Kings 20:5-7

5“Return, and say to Hezekiah the leader of My people, thus says Adonai, the God of your father David: ‘I have heard your prayer and I have seen your tears. Behold, I am going to heal you. On the third day you will go up to the House of Adonai.

6Then I will add 15 years to your life. I will deliver you and this city from the hand of the king of Assyria; I will defend this city for My own sake, and for My servant David’s sake.’”

7Then Isaiah said, “Take a cake of figs.” So they took one and laid it on the boil, and he recovered.
