Numbers 18:15-16

New English Translation

¹⁵ The firstborn of every womb which they present to the Lord, whether human or animal, will be yours. Nevertheless, the firstborn sons you must redeem,^[a] and the firstborn males of unclean animals you must redeem. ¹⁶ And those that must be redeemed you are to redeem when they are a month old, according to your estimation, for five shekels of silver according to the sanctuary shekel (which is twenty gerahs).
