Numbers 18:20-26

ISV^{(i) 20} Land Prohibited to Descendants of LeviThen the LORD instructed Aaron, “You are not to have any inheritance in the land, nor are you to have any portion among the people. I am your portion and your inheritance among the Israelis. ²¹ As to the descendants of Levi, certainly I’ve given all the tithes in Israel as their inheritance in return for their services that they perform at the Tent of Meeting. ²² Therefore, the Israelis need no longer come to the Tent of Meeting, so they won’t suffer the consequences of their sin and die. ²³ The descendants of Levi are to perform the service of the Tent of Meeting and they are to bear their iniquity. This is to be a statute forever, throughout your generations, that they are not to receive an inheritance among the Israelis, ²⁴ because I’ve given to the descendants of Levi the tithes that the Israelis bring to the LORD as raised offering. Therefore I told them that, unlike the Israelis, they won’t receive an inheritance.”
²⁵ Offerings Given to the Descendants of LeviThen the LORD instructed Moses, ²⁶ “Tell the descendants of Levi that when they receive tithes from the Israelis (the tithes that I’ve given you from them as an inheritance), you are to offer a tenth of it as a raised offering for the LORD.
