'Steps' in the Bible

So Isaiah replied, "This will be your sign from the LORD that the LORD will do what he has promised. Shall the shadow go forward ten steps or go back ten steps?"

Hezekiah answered, "It's an easy thing for a shadow to lengthen ten steps. So let the shadow go backward ten steps."

So Isaiah cried out to the LORD, who brought the shadow back ten steps after it had gone down the stairway of Ahaz.
