Exodus 25:18-22

18And make two cherubim out of hammered gold at the ends of the cover. 19Make one cherub on one end and the second cherub on the other; make the cherubim of one piece with the cover, at the two ends. 20The cherubim are to have their wings spread upward, overshadowing the cover with them. The cherubim are to face each other, looking toward the cover. 21Place the cover on top of the ark and put in the ark the tablets of the covenant law that I will give you. 22There, above the cover between the two cherubim that are over the ark of the covenant law, I will meet with you and give you all my commands for the Israelites.
