Exodus 25:16-20

You shall put into the ark the testimony which I shall give you.

“And you shall make an atoning cover of pure gold, two and a half cubits long and one and a half cubits wide.

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

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

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