Exodus 29:33

‘And he shall lay his hand on the head of the burnt offering, that it may be accepted for him to make atonement on his behalf.

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,

‘No layman, however, is to eat the holy gift; a foreign resident with the priest or a hired man shall not eat of the holy gift.

“Have you not driven out the priests of Yahweh, the sons of Aaron and the Levites, and made for yourselves priests like the peoples of other lands? Whoever comes to ordain himself with a bull from the herd and seven rams, even he may become a priest of what are no gods.
