Isaiah 38:6-8

Young's Literal Translation

⁶ and out of the hand of the king of Asshur I deliver thee and this city, and have covered over this city.

⁷ And this [is] to thee the sign from Jehovah, that Jehovah doth this thing that He hath spoken.

⁸ Lo, I am bringing back the shadow of the degrees that it hath gone down on the degrees of Ahaz, by the sun, backward ten degrees:' and the sun turneth back ten degrees in the degrees that it had gone down.
