Numbers 18:24

²²And the children of Israel shall no more draw nigh to the tabernacle of witness to incur fatal guilt.

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.

— Numbers 18:24 —

²⁵And the Lord spoke to Moses, saying,

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.
