⁹ And Isaiah said, “This shall be ^(A)the sign to you from the Lord, that the Lord will do the thing that he has promised: shall the shadow go forward ten steps, or go back ten steps?” ¹⁰ And Hezekiah answered, “It is an easy thing for the shadow ^(B)to lengthen ten steps. Rather let the shadow go back ten steps.”
