Exodus 25:15-19
English Standard Version
Chapter 25
15The poles shall remain in the rings of the ark; they shall not be taken from it. 16And you shall put into the ark the testimony that I shall give you.
17"You shall make a mercy seat of pure gold. Two cubits and a half shall be its length, and a cubit and a half its breadth.
18And you shall make two cherubim of gold; of hammered work shall you make them, on the two ends of the mercy seat.
19Make one cherub on the one end, and one cherub on the other end. Of one piece with the mercy seat shall you make the cherubim on its two ends.
