Numbers 18:16-22

¹⁶Those that are to be bought back by the people must be bought back after becoming one month old. Then the people may buy them back, for the price of five shekels, by the standard weight of the sanctuary shekel, which equals twenty gerahs.

¹⁷But the firstborn of a cow, or the firstborn of a sheep, or the firstborn of a goat—you must not buy back these animals; they are set apart to me. You must sprinkle their blood on the altar and burn their fat as an offering made by fire, an aroma pleasing to Yahweh.

¹⁸Their meat will be yours. Like the raised breast and the right thigh, their meat will be yours.

¹⁹All the holy offerings that the people of Israel present to Yahweh, I have given to you, and to your sons and to your daughters with you, as a continual share. It is an everlasting covenant of salt, a binding covenant forever, before Yahweh for both you and your descendants with you.”

²⁰Yahweh said to Aaron, “You will have no inheritance in the people's land, nor will you have any share of property among the people. I am your share and inheritance among the people of Israel.

²¹To the descendants of Levi, look, I have given all the tithes in Israel as their inheritance in return for the service that they provide in working at the tent of meeting.

²²From now on the people of Israel must not come near the tent of meeting, or they will be responsible for this sin and die.
