Exodus 25:18-21
18
You shall make two cherubim of hammered gold. You shall make them at the two ends of the mercy seat.
19
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.
20
The 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.
21
You shall put the mercy seat on top of the ark, and in the ark you shall put the testimony that I will give you.
