Exodus 40:15 WBT

¹³  And thou shalt put upon Aaron the holy garments, and anoint him, and sanctify him; that he may minister to me in the priest's office.

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

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

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

¹⁷  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.
