These portions were distributed because Manasseh’s daughters were given an inheritance along with his sons, while Gilead belonged to Manasseh’s other descendants.
Their territory extended from Mahanaim and included all of Bashan (the whole kingdom of King Og of Bashan) and all 60 settlements of Jair that were in Bashan.
It also included half of Gilead with Ashtaroth and Edrei, the royal cities of Og in Bashan. They were given to half the families of Machir, son of Manasseh, ⌞for their inheritance⌟.
Moses had given land in Bashan as an inheritance to half of Manasseh, and Joshua had given the other half of the tribe their land with their relatives west of the Jordan. When Joshua sent them home, he blessed them.
