Numbers 18:14-16 Common English Bible (CEB)
14 Everything that is devoted to the Lord in Israel will be yours. 15 Any oldest male from the womb of any living thing that is presented to the Lord, whether human or animal, will be yours. However, you will redeem the oldest males of humans and of unclean animals. 16 Their redemption price from one month of age you will calculate at five shekels of silver according to the sanctuary shekel, which is twenty gerahs.
