15. Every living thing that opens the womb, human being and beast alike, such as are to be offered to the Lord, shall be yours; but you must redeem the firstborn of human beings, as well as redeem the firstborn of unclean animals.
16. For the redemption price of a son, when he is a month old, you shall pay the equivalent of five silver shekels according to the sanctuary shekel, that is, twenty gerahs.
17. But the firstborn of cattle, or the firstborn of sheep or the firstborn of goats you shall not redeem; they are holy. Their blood you must splash on the altar and their fat you must burn as an oblation of pleasing aroma to the Lord.
18. Their meat, however, shall be yours, just as the brisket of the elevated offering and the right thigh belong to you.
19. As a perpetual due I assign to you and to your sons and daughters with you all the contributions of holy things which the Israelites set aside for the Lord; this is a covenant of salt to last forever before the Lord, for you and for your descendants with you.
