'Backs' in the Bible

Then he brought me to the inner court of the Lord's house. Right there at the entrance to the Lord's temple, between the porch and the altar, were about twenty-five men with their backs to the Lord's temple, facing east -- they were worshiping the sun toward the east!

along with their entire bodies, their backs, their hands, and their wings. The wheels of the four of them were full of eyes all around.
