Exodus 37:6

3 and he casteth for it four rings of gold, on its four feet, even two rings on its one side, and two rings on its second side;

4 and he maketh staves of shittim wood, and overlayeth them with gold,

5 and he bringeth in the staves into the rings, by the sides of the ark, to bear the ark.

6 And he maketh a mercy-seat of pure gold, two cubits and a half its length, and a cubit and a half its breadth;

7 and he maketh two cherubs of gold, of beaten work he hath made them, at the two ends of the mercy-seat;

8 one cherub at the end on this [side], and one cherub at the end on that, out of the mercy-seat he hath made the cherubs, at its two ends;

9 and the cherubs are spreading out wings on high, covering over the mercy-seat with their wings, and their faces [are] one towards another; towards the mercy-seat have the faces of the cherubs been.
