Exodus 25:16-21

ISV(i) 16 You are to put the Testimony that I will give you into the ark.
17 “You are to make a Mercy Seat of pure gold, two and a half cubits long and one and a half cubits wide. 18 You are to make two cherubim of gold; you are to make them of hammered work at the two ends of the Mercy Seat. 19 Place one cherub at one end and one cherub at the other end. You are to make the cherubim at the two ends of the Mercy Seat, and of one piece with it. 20 The cherubim are to spread their wings upward, covering the Mercy Seat with their wings and facing each other. The faces of the cherubim is to be turned toward the Mercy Seat. 21 You are to put the Mercy Seat on top of the ark, and put the Testimony that I’ll give you into the ark.
