'Ordination' in the Bible

This is the law of the burnt offering, the grain offering and the sin offering and the guilt offering and the ordination offering and the sacrifice of peace offerings,

Then he presented the second ram, the ram of ordination, and Aaron and his sons laid their hands on the head of the ram.

Then Moses took them from their hands and offered them up in smoke on the altar with the burnt offering. They were an ordination offering for a soothing aroma; it was an offering by fire to the Lord.

Moses also took the breast and presented it for a wave offering before the Lord; it was Moses’ portion of the ram of ordination, just as the Lord had commanded Moses.

Then Moses said to Aaron and to his sons, “Boil the flesh at the doorway of the tent of meeting, and eat it there together with the bread which is in the basket of the ordination offering, just as I commanded, saying, ‘Aaron and his sons shall eat it.’

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.
