Isaiah 38:6-8

Complete Jewish Bible

⁶ Also I will rescue you and this city from the power of the king of Ashur; I will defend this city. ⁷ The sign for you from Adonai that Adonai will do what he said is ⁸ that I will cause the shadow of the sundial, which has started going down on the sundial of Achaz, to go backward ten intervals.’” So the sun went back ten intervals of the distance it had already gone down.
