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

This was a special stairway built for King Ahaz in such a way that its steps marked the hours of daylight as the sun's rays advanced along them. The staircase served to tell the time during the day. See "stairway of Ahaz" in 2 Kings 20:11.
