'Ordain' in the Bible
You are to put them on Aaron your brother, and on his sons with him, and you are to anoint them, ordain them, and consecrate them to serve as my priests.
You are to gird Aaron and his sons with sashes and tie headdresses on them. The priesthood is to belong to them by perpetual ordinance, and you are to ordain Aaron and his sons.
You are to do this for Aaron and his sons, just as I've commanded you. You are to ordain them for seven days,
Furthermore, you are not to go out past the entrance to the Tent of Meeting until the days of your ordination have been completed, since it will take seven days to ordain you.
Do not ordain anyone hastily. Do not participate in the sins of others. Keep yourself pure.
