Exodus 25:18-20

18You shall make two cherubim of gold; make them of hammered work 1at the two ends of the atoning cover.

19Make one cherub 2at one end and one cherub 3at the other end; you shall make the cherubim of one piece 4with the atoning cover at its two ends.

20And 5the cherubim shall have their wings spread upward, covering the atoning cover with their wings and 6facing one another; the faces of the cherubim are to be turned toward the atoning cover.
