Exodus 40:17-20

17So the Tabernacle was set up on the first day of the first month of the second year.

18Moses erected the Tabernacle by setting down its bases, inserting the frames, attaching the crossbars, and setting up the posts.

19Then he spread the coverings over the Tabernacle framework and put on the protective layers, just as the Lord had commanded him.

20He took the stone tablets inscribed with the terms of the covenant and placed them inside the Ark. Then he attached the carrying poles to the Ark, and he set the Ark’s cover—the place of atonement—on top of it.
