Exodus 25:17-19

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

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

Make 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.
