Numbers 18:25

²³And the Levite himself shall perform the service of the tabernacle of witness; and they shall bear their iniquities, it is a perpetual statute throughout their generations; and in the midst of the children of Israel they shall not receive an inheritance.

²⁴Because I have given as a distinct portion to the Levites for an inheritance the tithes of the children of Israel, whatsoever they shall offer to the Lord; therefore I said to them, In the midst of the children of Israel they shall have no inheritance.

— Numbers 18:25 —

²⁶Thou shalt also speak to the Levites, and shalt say to them, If ye take the tithe from the children of Israel, which I have given you from them for an inheritance, then shall ye separate from it a heave offering to the Lord, a tenth of the tenth.

²⁷And your heave offerings shall be reckoned to you as corn from the floor, and an offering from the winepress.
