Numbers chapter 18

After reading chapter 18:

*Now Yahweh tells Aaron that he and his sons, and their descendants, will be the only ones responsible for the altar, the sanctuary, and the duties inside the tabernacle. This service is given to them as a priesthood.  If anyone else comes near the sanctuary, they will die. The other Levites are given to the priests to be helpers with all the stuff and activities outside the tent.

* All the wave offerings, first fruit offerings, grain offerings, sin offerings, and  guilt offerings that the Israelites give to Yahweh, become the priests'. This is Yahweh's gift to them and an everlasting covenant, or at least Aaron said it was. They must take his word for it, or rather the word of the person who wrote about it, who was probably a priest. They may share it with others in their household who are ceremonially clean, of course. However, they will get none of the promised land as an inheritance. Who needs land when they have a guaranteed steady supply of food and money?

*For their service, the rest of the Levites get all the tithes that the Israelites bring to Yahweh. They will also have no inherited land. Of the tithes that the Levites get from the Israelites,  they must take the best and holiest tenth and give it to Aaron and his sons. That is their tithe to the lord, so they won't be guilty and die. How nice for the priests that the lord is so generous and gives them all his stuff, which he has no use for anyway.
