Exodus 25:19-20

And make one cherub on the one end, and the other cherub on the other end: {even} of the mercy seat shall ye make the cherubims on the two ends thereof. {of...: or, of the matter of the mercy seat} And the cherubims shall stretch forth {their} wings on high, covering the mercy seat with their wings, and their faces {shall look} one to another; toward the mercy seat shall the faces of the cherubims be.
