Yeshayah 38:6-8

Orthodox Jewish Bible

⁶ And I will deliver thee and this Ir out of the hand of Melech Ashur (Assyria); and I will defend HaIr Hazot.

⁷ And this shall be HaOt (the Sign) unto thee from Hashem, that Hashem will do this thing that He hath spoken;

⁸ Hineni, I will bring again the tzel (shadow) of the hama’alot (the steps), which has gone down with the shemesh on the Ma’alot Achaz (sundial of Ahaz), so that it goes eser ma’alot (ten steps) backward. So the shemesh went back eser maalot (ten steps) on the ma’alot on which it had gone down.
