Numbers 18:15-17 And every firstling of all flesh, which they bring for the Lord, whether of man or beast, shall belong to thee: but the first born of man shall be redeemed, and thou shalt cause them to redeem the firstlings of all cattle which are not clean.

Thomson⁽ⁱ⁾ ¹⁵ And every firstling of all flesh, which they bring for the Lord, whether of man or beast, shall belong to thee: but the first born of man shall be redeemed, and thou shalt cause them to redeem the firstlings of all cattle which are not clean. ¹⁶ Now the redemption of the former, at a month old, shall be the set price of five shekels after the holy shekel, which is twenty oboli: ¹⁷ but the firstlings of kine, and the firstlings of sheep, and the firstlings of goats, thou shalt not suffer them to redeem. They are hallowed; therefore thou shalt pour out their blood before the altar, and offer their suet as an offering of homage, for a smell of fragrance for the Lord.
