Numbers 18:8-13 Christian Standard Bible (CSB)
Support for the Priests and Levites
8 Then the Lord spoke to Aaron, “Look, I have put you in charge of the contributions brought to me. As for all the holy offerings of the Israelites, I have given them to you and your sons as a portion and a permanent statute. 9 A portion of the holiest offerings kept from the fire will be yours; every one of their offerings that they give me, whether the grain offering, sin offering, or guilt offering will be most holy for you and your sons. 10 You are to eat it as a most holy offering.[a] Every male may eat it; it is to be holy to you.
11 “The contribution of their gifts also belongs to you. I have given all the Israelites’ presentation offerings to you and to your sons and daughters as a permanent statute. Every ceremonially clean person in your house may eat it. 12 I am giving you all the best of the fresh oil, new wine, and grain, which the Israelites give to the Lord as their firstfruits. 13 The firstfruits of all that is in their land, which they bring to the Lord, belong to you. Every clean person in your house may eat them.
Nehemiah 10:35-37 Christian Standard Bible (CSB)
35 We will bring the firstfruits of our land and of every fruit tree to the Lord’s house year by year. 36 We will also bring the firstborn of our sons and our livestock, as prescribed by the law, and will bring the firstborn of our herds and flocks to the house of our God, to the priests who serve in our God’s house. 37 We will bring a loaf from our first batch of dough to the priests at the storerooms of the house of our God. We will also bring the firstfruits of our grain offerings, of every fruit tree, and of the new wine and fresh oil. A tenth of our land’s produce belongs to the Levites, for the Levites are to collect the one-tenth offering in all our agricultural towns.
