Numbers 18:25–32

²⁵The Lord spoke to Moses, saying, ²⁶“You shall say to the Levites: When you receive from the Israelites the tithe that I have given you from them for your portion, you shall set apart an offering from it to the Lord, a tithe of the tithe.^{* 27}It shall be reckoned to you as your gift, the same as the grain of the threshing floor and the fullness of the winepress. ²⁸Thus you also shall set apart an offering to the Lord from all the tithes that you receive from the Israelites, and from them you shall give the Lord’s offering to the priest Aaron.^{* 29}Out of all the gifts to you, you shall set apart every offering due to the Lord; the best of all of them is the part to be consecrated. ³⁰Say also to them: When you have set apart the best of it, then the rest shall be reckoned to the Levites as produce of the threshing floor and as produce of the winepress. ³¹You may eat it in any place, you and your households, for it is your payment for your service in the tent of meeting. ³²You shall incur no guilt by reason of it, when you have offered the best of it. But you shall not profane the holy gifts of the Israelites, on pain of death.”^*
