Exodus 25:18

16You shall put the covenant which I shall give you into the ark.

17You shall make a mercy seat of pure gold. Two and a half cubits shall be its length, and a cubit and a half its width.

18You shall make two cherubim of hammered gold. You shall make them at the two ends of the mercy seat.

19Make one cherub at the one end, and one cherub at the other end. You shall make the cherubim on its two ends of one piece with the mercy seat.

20The cherubim shall spread out their wings upward, covering the mercy seat with their wings, with their faces toward one another. The faces of the cherubim shall be toward the mercy seat.
