2 Kings 20:10-11

20:10 Hezekiah answered, “It is easy for the shadow to lengthen ten steps, but not for it to go back ten steps.” 20:11 Isaiah the prophet called out to the Lord, and the Lord made the shadow go back ten steps on the stairs of Ahaz.

Isaiah 38:8

38:8 Look, I will make the shadow go back ten steps on the stairs of Ahaz.” And then the shadow went back ten steps.
