Isaiah 38:7-8 ▼

7 “Now this shall be the sign to you from Yahweh, that Yahweh will do this word that He has spoken:

8 Behold, I will cause the shadow on the stairway, which has gone down with the sun on the stairway of Ahaz, to go back ten steps.” So the sun’s shadow went back ten steps on the stairway on which it had gone down.
