Numbers 18:20-22

King James Version

²⁰ And the Lord spake unto Aaron, Thou shalt have no inheritance in their land, neither shalt thou have any part among them: I am thy part and thine inheritance among the children of Israel.

²¹ And, behold, I have given the children of Levi all the tenth in Israel for an inheritance, for their service which they serve, even the service of the tabernacle of the congregation.

²² Neither must the children of Israel henceforth come nigh the tabernacle of the congregation, lest they bear sin, and die.
