Numbers 18:14-16

Lexham English Bible

¹⁴ All consecrated possessions^[a] in Israel will be for you. ¹⁵ All the first offspring of a womb of any creature that they offer to Yahweh, whether human or animal, will be yours; you will surely redeem the firstborn of the human and the unclean firstborn of the animal. ¹⁶ As to their price of redemption, from a one-month-old^[b] you will redeem them according to your proper value, five shekels of silver according to the shekel of the sanctuary, which is twenty gerah.
