Numbers 18:13-15

New Revised Standard Version Catholic Edition

¹³ The first fruits of all that is in their land, which they bring to the Lord, shall be yours; everyone who is clean in your house may eat of it. ¹⁴ Every devoted thing in Israel shall be yours. ¹⁵ The first issue of the womb of all creatures, human and animal, which is offered to the Lord, shall be yours; but the firstborn of human beings you shall redeem, and the firstborn of unclean animals you shall redeem.
