Exodus 40:19

And it came to pass in the first month in the second year, on the first day of the month, that the tabernacle was reared up.

And Moses reared up the tabernacle, and fastened his sockets, and set up the boards thereof, and put in the bars thereof, and reared up his pillars.

And he took and put the testimony into the ark, and set the staves on the ark, and put the mercy seat above upon the ark:

And he brought the ark into the tabernacle, and set up the vail of the covering, and covered the ark of the testimony; as the LORD commanded Moses.
