Behold, I will bring again the shadow of the degrees, which is gone down in the sun dial of Ahaz, ten degrees backward. So the sun returned ten degrees, by which degrees it was gone down.
Berean Study Bible (BSB) - Isaiah 38:8 >I will make the sun’s shadow that falls on the stairway of Ahaz go back ten steps.’” So the sunlight went back the ten steps it had descended.
