Exodus 40:19-21

40:19 Then he spread the tent over the tabernacle and put the covering of the tent over it, as the Lord had commanded Moses. 40:20 He took the testimony and put it in the ark, attached the poles to the ark, and then put the atonement lid on the ark. 40:21 And he brought the ark into the tabernacle, hung the protecting curtain, and shielded the ark of the testimony from view, just as the Lord had commanded Moses.
