Joshua told the Reubenites, Gadites, and the half tribe of Manasseh:

Then Joshua summoned the Reubenites, Gadites, and the half-tribe of Manasseh

Then we took their land and gave it as an inheritance to Reuben, Gad, and half the tribe of Manasseh.

This is the land we brought under our control at that time: The territory extending from Aroer ¹  by the Wadi Arnon and half the Gilead hill country with its cities I gave to the Reubenites and Gadites. ² 

To the Reubenites and Gadites I allocated the territory extending from Gilead as far as Wadi Arnon (the exact middle of the wadi was a boundary) all the way to the Wadi Jabbok, the Ammonite border.

Moses the Lord’s servant and the Israelites defeated them and Moses the Lord’s servant assigned their land ¹  to Reuben, Gad, and the half tribe of Manasseh.

So the God of Israel stirred up ¹  King Pul of Assyria (that is, King Tiglath-pileser of Assyria), ²  and he carried away the Reubenites, Gadites, and half-tribe of Manasseh and took them to Halah, Habor, Hara, and the river of Gozan, where they remain to this very day.
