Exodus 37:6-9
He made the atonement cover of pure gold - two and a half cubits long and a cubit and a half wide. Then he made two cherubim out of hammered gold at the ends of the cover.
He made one cherub on one end and the second cherub on the other; at the two ends he made them of one piece with the cover.
The cherubim had their wings spread upward, overshadowing the cover with them. The cherubim faced each other, looking toward the cover.
