Manasseh was allotted ten shares of land, ¹  in addition to the land of Gilead and Bashan east of the Jordan,

The tribe of Manasseh, Joseph’s firstborn son, was also allotted land. ¹  The descendants of Makir, Manasseh’s firstborn and the father of Gilead, received land, for they were warriors. ²  They were assigned Gilead and Bashan. ³ 

and ruled over Mount Hermon, Salecah, all of Bashan to the border of the Geshurites and Maacathites, and half of Gilead as far as the border of King Sihon of Heshbon.

Their territory included Jazer, all the cities of Gilead, and half of Ammonite territory ¹  as far as Aroer near ²  Rabbah.

Half of Gilead, Ashtaroth, and Edrei, cities in the kingdom of Og in Bashan, were assigned to the descendants of Makir son of Manasseh, to half the descendants of Makir by their clans.

for the daughters of Manasseh were assigned land among his sons. The land of Gilead belonged to the rest of the descendants of Manasseh.

They went to the land of Gilead to the Reubenites, Gadites, and the half-tribe of Manasseh, and said to them:

King Sihon of the Amorites who lived ¹  in Heshbon and ruled from Aroer (on the edge of the Arnon Valley) – including the city in the middle of the valley ²  and half of Gilead – all the way to the Jabbok Valley bordering Ammonite territory.

The Israelites sent Phinehas, son of Eleazar, the priest, to the land of Gilead to the Reubenites, Gadites, and the half-tribe of Manasseh.

Phinehas, son of Eleazar, the priest, and the leaders left the Reubenites and Gadites in the land of Gilead and reported back to the Israelites in the land of Canaan. ¹ 

So the Reubenites, Gadites, and half-tribe of Manasseh left the Israelites in Shiloh in the land of Canaan and headed home to their own land in Gilead, ¹  which they acquired by the Lord’s command through Moses.
