Exodus 25:18-20

Young's Literal Translation

¹⁸ and thou hast made two cherubs of gold, beaten work dost thou make them, at the two ends of the mercy-seat;

¹⁹ and make thou one cherub at the end on this side, and one cherub at the end on that; at the mercy-seat ye do make the cherubs on its two ends.

²⁰ `And the cherubs have been spreading out wings on high, covering the mercy-seat over with their wings, and their faces [are] one towards another -- towards the mercy-seat are the faces of the cherubs.
