Will the shadow go forward ten steps, or go back ten steps?

"Do you want Yahweh to make the shadow caused by the sunlight on the stairway to go forward ten steps or to go back ten steps?"

ten steps

A special stairway built for King Ahaz in such a way that the steps marked the hours of daylight as the sun's rays advanced along them; thus telling the time during the day. See "stairway of Ahaz" in 2 Kings 20:11.
