'Ordain' in the Bible

You shall put them on Aaron your brother and on his sons with him; and you shall anoint them and ordain them and consecrate them, that they may serve Me as priests.

You shall gird them with sashes, Aaron and his sons, and bind caps on them, and they shall have the priesthood by a perpetual statute. So you shall ordain Aaron and his sons.

“Thus you shall do to Aaron and to his sons, according to all that I have commanded you; you shall ordain them through seven days.

You shall not go outside the doorway of the tent of meeting for seven days, until the day that the period of your ordination is fulfilled; for he will ordain you through seven days.
