Numbers 18:16-24
English Standard Version
Chapter 18
16And their redemption price (at a month old you shall redeem them) you shall fix at five shekels in silver, according to the shekel of the sanctuary, which is twenty gerahs. 17But the firstborn of a cow, or the firstborn of a sheep, or the firstborn of a goat, you shall not redeem; they are holy. You shall sprinkle their blood on the altar and shall burn their fat as a food offering, with a pleasing aroma to the Lord. 18But their flesh shall be yours, as the breast that is waved and as the right thigh are yours. 19All the holy contributions that the people of Israel present to the Lord I give to you, and to your sons and daughters with you, as a perpetual due. It is a covenant of salt forever before the Lord for you and for your offspring with you." 20And the Lord said to Aaron, "You shall have no inheritance in their land, neither shall you have any portion among them. I am your portion and your inheritance among the people of Israel.
21"To the Levites I have given every tithe in Israel for an inheritance, in return for their service that they do, their service in the tent of meeting,
22so that the people of Israel do not come near the tent of meeting, lest they bear sin and die.
23But the Levites shall do the service of the tent of meeting, and they shall bear their iniquity. It shall be a perpetual statute throughout your generations, and among the people of Israel they shall have no inheritance.
24For the tithe of the people of Israel, which they present as a contribution to the Lord, I have given to the Levites for an inheritance. Therefore I have said of them that they shall have no inheritance among the people of Israel."
