Exodus 40:16

14And thou shalt bring his sons, and clothe them with coats:

15And thou shalt anoint them, as thou didst anoint their father, that they may minister unto me in the priest’s office: for their anointing shall surely be an everlasting priesthood throughout their generations.

16Thus did Moses: according to all that the LORD commanded him, so did he.

17And 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.

18And 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.
