Numbers 18:14-16 Christian Standard Bible (CSB)
14 “Everything in Israel that is permanently dedicated to the Lord belongs to you. 15 The firstborn of every living thing, human or animal, presented to the Lord belongs to you. But you must certainly redeem a human firstborn, and redeem the firstborn of an unclean animal. 16 You will pay the redemption price for a month-old male according to your assessment: five shekels[a] of silver by the standard sanctuary shekel, which is twenty gerahs.
