Exodus 37:6

4He made poles of acacia wood and overlaid them with gold.

5He put the poles into the rings on the sides of the ark, to bear the ark.

6He made a mercy seat of pure gold. Its length was two and a half cubits, and a cubit and a half its width.

7He made two cherubim of gold. He made them of beaten work, at the two ends of the mercy seat:

8one cherub at the one end, and one cherub at the other end. He made the cherubim of one piece with the mercy seat at its two ends.
