15. Everything that first opens the womb in all flesh, which they bring to the Lord, whether it be of men or beasts, shall be yours. Nevertheless the firstborn of man you shall surely redeem, and the firstling of unclean beasts you shall redeem.
16. And those that are to be redeemed of them, from a month old shall you redeem, according to your estimate [of their age], for the fixed price of five shekels in silver, according to the shekel of the sanctuary, which is twenty gerahs.
17. But the firstling of a cow or of a sheep or of a goat you shall not redeem. They [as the firstborn of clean beasts belong to God and] are holy. You shall sprinkle their blood upon the altar and shall burn their fat for an offering made by fire, for a sweet and soothing odor to the Lord.
18. And the flesh of them shall be yours, as the wave breast and as the right shoulder are yours.
19. All the heave offerings [the lifted-out and kept portions] of the holy things which the Israelites give to the Lord I give to you and to your sons and your daughters with you, as a continual debt forever. It is a covenant of salt [that cannot be dissolved or violated] forever before the Lord for you [Aaron] and for your posterity with you.
20. And the Lord said to Aaron, You shall have no inheritance in the land [of the Israelites], neither shall you have any part among them. I am your portion and your inheritance among the Israelites.
