Exodus 37:4-8

And he made poles of acacia wood and overlaid them with gold.

He put the poles into the rings on the sides of the ark, to carry it.

He also made an atoning cover of pure gold, two and a half cubits long and one and a half cubits wide.

And he made two cherubim of gold; he made them of hammered work at the two ends of the atoning cover:

one cherub at the one end and one cherub at the other end; he made the cherubim of one piece with the atoning cover at the two ends.
