JOS 18:7

7 But the tribe of Levi will not be allotted any land, because their [reward is that they will be] Yahweh’s priests. The tribes of Gad, Reuben, and half the tribe of Manasseh have already been allotted their land on the east side of the Jordan [River], just as Moses, the man who served God [well], decided, [so they will not get any more land].”
