Numbers 18:12-21

¹²I am giving you all the best olive oil and all the best new wine and grain that the Israelites give as firstfruits to the Lord.

¹³The firstfruits of all the crops they produce in their land that they bring to the Lord are yours. Everyone in your family who is ceremonially clean is allowed to eat them.

¹⁴Everything in Israel that is dedicated to the Lord is yours.

¹⁵Every firstborn, whether human or animal, that is offered to the Lord is yours. But you must buy back every firstborn son and every firstborn male of unclean animals.

¹⁶When they are one month old you shall pay the redemption price of five shekels of silver, (using the sanctuary shekel standard), equivalent to twenty gerahs.

¹⁷But you are not allowed to redeem the firstborn of an ox, a sheep, or a goat because they are holy. You shall sprinkle their blood on the altar, and burn their fat as a burnt offering accepted by the Lord.

¹⁸Their meat is yours, in the same way that the breast and right thigh of the wave offering are yours.

¹⁹I am giving all the voluntary gifts that the Israelites present to the Lord to you and to your sons and daughters as a permanent rule. It is a permanent agreement of salt before the Lord for you and your descendants.”

²⁰“You won't possess property in their country, and you won't have a share in their land. I am your share and your possession among the Israelites.

²¹Instead I have given the Levites all the tithes in Israel as compensation for the service they provide in doing the work in the Tent of Meeting.
