17 Only the firstborn of an ox or the firstborn of a sheep or the firstborn of a goat you will not redeem; they are holy. Their blood you will sprinkle over the altar, and their fat you will turn into smoke as an offering made by fire, a fragrance of appeasement for Yahweh.
18 But their flesh will be for you like the breast section of the wave offering, and it will be for you like the right upper thigh.
19 All the contributions of holiness that the Israelites offer to Yahweh I have given to you and your sons and your daughters with you as an eternal decree; it is an eternal covenant of salt before Yahweh to you and your offspring with you.”
20 Then Yahweh said to Aaron, “You will not receive an inheritance in their land, and there will not be a plot of ground for you in the midst of the Israelites.
21 “Behold, I have given to the descendants of Levi every tithe in Israel as an inheritance in return for their service, which they are doing, the work of the tent of assembly.
22 The Israelites will not come near again to the tent of assembly, or they will bear sin and die.
23 The Levites will perform the service of the tent of assembly, and they will bear their guilt, an eternal decree for all your generations. But they will not receive an inheritance in the midst of the Israelites
