Meanwhile, Hezekiah had said to Isaiah, “What sign will the Lord give to prove that he will heal me and that I will go to the Temple of the Lord three days from now?”
Then Isaiah said to Hezekiah, “Here is the proof that what I say is true: “This year you will eat only what grows up by itself, and next year you will eat what springs up from that. But in the third year you will plant crops and harvest them; you will tend vineyards and eat their fruit.
“Go back to Hezekiah, the leader of my people. Tell him, ‘This is what the Lord, the God of your ancestor David, says: I have heard your prayer and seen your tears. I will heal you, and three days from now you will get out of bed and go to the Temple of the Lord.
Isaiah replied, “This is the sign from the Lord to prove that he will do as he promised. Would you like the shadow on the sundial to go forward ten steps or backward ten steps?”
All right then, the Lord himself will give you the sign. Look! The virgin will conceive a child! She will give birth to a son and will call him Immanuel (which means ‘God is with us’).
