Exodus 40:18-20

40:18 When Moses set up the tabernacle and put its bases in place, he set up its frames, attached its bars, and set up its posts. 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.
