Exodus 37:7-9

7And he made two cherubim of gold; of beaten work made he them, at the two ends of the mercy-seat;

8one cherub at the one end, and one cherub at the other end: of one piece with the mercy-seat made he the cherubim at the two ends thereof.

9And the cherubim spread out their wings on high, covering the mercy-seat with their wings, with their faces one to another; toward the mercy-seat were the faces of the cherubim.
