'Backs' in the Bible

He brought me into the inner court of Yahweh's house; and see, at the door of the temple of Yahweh, between the porch and the altar, were about twenty-five men, with their backs toward the temple of Yahweh, and their faces toward the east; and they were worshipping the sun toward the east.

Their whole body, and their backs, and their hands, and their wings, and the wheels, were full of eyes all around, [even] the wheels that the four of them had.
