Numbers 18:15-17

¹⁵Whatever thing cometh first forth of the womb of all flesh, which they offer to the Lord, whether it is of men, either of beasts, it shall be of thy right; so only that thou take price for the first begotten child of man, and that thou make each beast that is unclean to be bought again; (Whatever thing of all flesh that cometh forth first from the womb, whether it is of men, or of beasts, which they offer to the Lord, shall be thy right to have; so only that thou take payment in exchange, or as redemption, for the first-born of man, and that thou make each beast that is unclean to be bought back;)

¹⁶whose again-buying shall be after one month, for five shekels of silver, by the weight of the saintuary, (or whose redemption shall be after one month, for five shekels of silver, by the measure of the sanctuary); a shekel hath twenty halfpence.

¹⁷Forsooth thou shalt not make the first engendered of an ox, and of sheep, and of goat, to be again-bought, for those be hallowed to the Lord; only thou shalt pour the blood of those upon the altar, and thou shalt burn the inner fatness into sweetest odour to the Lord. (But thou shalt not allow the first-born of an ox, or of a sheep, or of a goat, to be bought back, for they be holy to the Lord; thou must throw their blood against the altar, and thou shalt burn their inner fatness to make the sweetest aroma to the Lord.)
