Exodus 37:9 (KJV)

And he made two cherubims of gold, beaten out of one piece made he them, on the two ends of the mercy seat;

One cherub on the end on this side, and another cherub on the other end on that side: out of the mercy seat made he the cherubims on the two ends thereof.

And the cherubims spread out their wings on high, and covered with their wings over the mercy seat, with their faces one to another; even to the mercy seatward were the faces of the cherubims.

And he made the table of shittim wood: two cubits was the length thereof, and a cubit the breadth thereof, and a cubit and a half the height thereof:

And he overlaid it with pure gold, and made thereunto a crown of gold round about.
