Numbers 18:14-16

New Century Version

¹⁴ “Everything in Israel that is given to the Lord is yours. ¹⁵ The first one born to any family, whether people or animals, will be offered to the Lord. And that will be yours. But you must make a payment for every firstborn child and every firstborn animal that is unclean. ¹⁶ When they are one month old, you must make a payment for them of two ounces of silver, as set by the Holy Place measure.
