2 Kings 20:9-10

New International Version

⁹ Isaiah answered, “This is the Lord’s sign^(A) to you that the Lord will do what he has promised: Shall the shadow go forward ten steps, or shall it go back ten steps?”

¹⁰ “It is a simple^(B) matter for the shadow to go forward ten steps,” said Hezekiah. “Rather, have it go back ten steps.”
