'Backs' in the Bible

So He brought me to the inner court of the Lord’s house, and there were about 25 men at the entrance of the Lord’s temple, between the portico and the altar, with their backs to the Lord’s temple and their faces turned to the east. They were bowing to the east in worship of the sun.

Their entire bodies, including their backs, hands, wings, and the wheels that the four of them had, were full of eyes all around.
