Exodus 37:6

3 And he cast for it four rings of gold, to be set by the four corners of it; even two rings upon the one side of it, and two rings upon the other side of it.

4 And he made staves of shittim wood, and overlaid them with gold.

5 And he put the staves into the rings by the sides of the ark, to bear the ark.

6 And he made the mercy seat of pure gold: two cubits and a half was the length thereof, and one cubit and a half the breadth thereof.

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

8 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.

9 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.
