Exodus 25:18-20

18And thou shalt make two cherubim of gold; of beaten work shalt thou make them, at the two ends of the mercy-seat. 19And make one cherub at the one end, and one cherub at the other end: of one piece with the mercy-seat shall ye make the cherubim on the two ends thereof. 20And the cherubim shall spread out their wings on high, covering the mercy-seat with their wings, with their faces one to another; toward the mercy-seat shall the faces of the cherubim be.
