"Instructions for the Levites The LORD spoke to Moses:"
— Numbers 18:25, NET Bible
No longer may the Israelites approach the tent of meeting, or else they will bear their sin and die.
But the Levites must perform the service of the tent of meeting, and they must bear their iniquity. It will be a perpetual ordinance throughout your generations that among the Israelites the Levites have no inheritance.
But I have given to the Levites for an inheritance the tithes of the Israelites that are offered to the LORD as a raised offering. That is why I said to them that among the Israelites they are to have no inheritance.”
Instructions for the Levites The LORD spoke to Moses:
“You are to speak to the Levites, and you must tell them,‘When you receive from the Israelites the tithe that I have given you from them as your inheritance, then you are to offer up from it as a raised offering to the LORD a tenth of the tithe.
And your raised offering will be credited to you as though it were grain from the threshing floor or as new wine from the winepress.
Thus you are to offer up a raised offering to the LORD of all your tithes which you receive from the Israelites; and you must give the LORD’s raised offering from it to Aaron the priest.
