'Backs' in the Bible

And He bringeth me in unto the inner court of the house of Jehovah, and lo, at the opening of the temple of Jehovah, between the porch and the altar, about twenty-five men, their backs toward the temple of Jehovah, and their faces eastward, and they are bowing themselves eastward to the sun.

And all their flesh, and their backs, and their hands, and their wings, and the wheels, are full of eyes round about; to them four are their wheels.
