2 Kings 20:8-10

Amplified Bible, Classic Edition

⁸ Hezekiah said to Isaiah, What shall be the sign that the Lord will heal me and that I shall go up into the house of the Lord on the third day?

⁹ And Isaiah said, This is the sign to you from the Lord that He will do the thing He has promised: shall the shadow [denoting the time of day] go forward ten steps, or go back ten steps?

¹⁰ Hezekiah answered, It is an easy matter for the shadow to go forward ten steps; so let the shadow go back ten steps.
