Numbers 18:13-15

Revised Standard Version

¹³ The first ripe fruits of all that is in their land, which they bring to the Lord, shall be yours; every one who is clean in your house may eat of it. ¹⁴ Every devoted thing in Israel shall be yours. ¹⁵ Everything that opens the womb of all flesh, whether man or beast, which they offer to the Lord, shall be yours; nevertheless the first-born of man you shall redeem, and the firstling of unclean beasts you shall redeem.
