Exodus 25:19KJV

17And thou shalt make a mercy seat pure gold: two cubits and a half the length thereof, and a cubit and a half the breadth thereof.

18And thou shalt make two cherubims gold, beaten work shalt thou make them, in the two ends of the mercy seat.

19And make one cherub on the one end, and the other cherub on the other end: of the mercy seat shall ye make the cherubims on the two ends thereof.

20And the cherubims shall stretch forth wings on high, covering the mercy seat with their wings, and their faces one to another; toward the mercy seat shall the faces of the cherubims be.

21And thou shalt put the mercy seat above upon the ark; and in the ark thou shalt put the testimony that I shall give thee.
