Exodus 25:16-22

And thou shalt put into the ark the testimony which I shall give thee. And thou shalt make a mercy-seat of pure gold: two cubits and a half shall be the length thereof, and a cubit and a half the breadth thereof. And thou shalt make two cherubim of gold; of beaten work shalt thou make them, at the two ends of the mercy-seat. And make one cherub at the one end, and one cherub at the other end: of one piece with the mercy-seat shall ye make the cherubim on the two ends thereof. And the cherubim shall spread out their wings on high, covering the mercy-seat with their wings, with their faces one to another; toward the mercy-seat shall the faces of the cherubim be. And thou shalt put the mercy-seat above upon the ark; and in the ark thou shalt put the testimony that I shall give thee. And there I will meet with thee, and I will commune with thee from above the mercy-seat, from between the two cherubim which are upon the ark of the testimony, of all things which I will give thee in commandment unto the children of Israel.
