15. The first offspring of the womb from all flesh, whether human or animal, offered to Adonai, is yours. However, you are to redeem the firstborn of man and the firstborn of unclean animals.
16. When they are a month old, you are to redeem them at the redemption price of five shekels of silver by the Sanctuary shekel, or 20 gerahs.
17. But the firstborn of the ox, sheep or goat you are not to redeem. They are holy. You are to sprinkle their blood on the altar, and their fat you are to burn as a fire offering, a pleasing aroma to Adonai.
18. Their meat—the breast of the wave offering and the right thigh—is yours.
19. Whatever is set aside from the holy offerings which Bnei-Yisrael present to Adonai, I have given to you, your sons and your daughters with you as a permanent share. It is an everlasting covenant of salt before Adonai for you and your offspring.”
20. Adonai said to Aaron, “You will have no inheritance in their land nor share among them. I am your portion and your share among Bnei-Yisrael.
21. See, I have given all the tithes in Israel to the sons of Levi as an inheritance in return for all the work of the service they are doing in the Tent of Meeting.
22. From now on, Bnei-Yisrael must never trespass the Tent of Meeting, or they will bear the consequences of their sin and die.
23. The Levites will perform the service of the Tent of Meeting. They will bear the responsibility for their iniquity. It is a permanent ordinance throughout your generations. So among Bnei-Yisrael they are to receive no inheritance.
24. For I have given the tithes that Bnei-Yisrael present to Adonai as an offering to the Levites as an inheritance. That is why I said they would receive no inheritance among Bnei-Yisrael.”
25. Adonai spoke to Moses saying,
26. “Speak now to the Levites and say to them: When you receive from Bnei-Yisrael the tithe which I have given to you as your inheritance, you are then to offer to Adonai a tithe of that tithe.
27. Your offering will be reckoned as grain from the threshing floor or the fullness of the winepress.
28. Thus you will also present an offering to Adonai from all your tithes that you receive from Bnei-Yisrael, and from that you are to give Adonai’s portion to Aaron the kohen.
