Exodus 40:20-21

20Moses took the two flat stones with God's special commands on them. He put them inside the Covenant Box. He put the poles through the rings on the box. He put the special lid on top of the box.

21Then he brought the Covenant Box into the tabernacle. He hung the special curtain to hide it, so that nobody could see it. He did this in the way that the Lord had commanded him.
