On the conquest of Bashan, see especially Numbers 32:33, etc. and notes.

The half tribe of Manasseh - When the tribes of Reuben and Gad requested to have their settlement on the east side of Jordan, it does not appear that any part of the tribe of Manasseh requested to be settled in the same place. But as this tribe was numerous, and had much cattle, Moses thought proper to appoint one half of it to remain on the east of Jordan, and the other to go over and settle on the west side of that river.

And Moses gave inheritance unto the half tribe of Manasseh,.... Whether at their request or of himself, there being land enough for them, and the two tribes of Gad and Reuben, is not certain:

and this is the possession of the half tribe of Manasseh, by their families; which is after related and described.

The territory of the half tribe of Manasseh extended from Mahanaim onwards, and embraced all Bashan, with the sixty Jair towns and the (northern) half of Gilead (see the comm. on Deuteronomy 3:13-15).

And Moses gave inheritance unto the half tribe of Manasseh: and this was the possession of the half tribe of the children of Manasseh by their families.

13:29 Of Manasseh - Not that thou desired it, as Reuben and Gad did, Numb 32:1, but partly as a recompence to Machir the Manassite, for his valiant acts against Og; and partly for the better defence of the other two tribes, by so considerable an accession to them, which also was without any inconvenience to them, because the country was too large for the two tribes of Reuben and Gad.

13:7-33 The land must be divided among the tribes. It is the will of God that every man should know his own, and not take that which is another's. The world must be governed, not by force, but right. Wherever our habitation is placed, and in whatever honest way our portion is assigned, we should consider them as allotted of God; we should be thankful for, and use them as such, while every prudent method should be used to prevent disputes about property, both at present and in future. Joshua must be herein a type of Christ, who has not only conquered the gates of hell for us, but has opened to us the gates of heaven, and having purchased the eternal inheritance for all believers, will put them in possession of it. Here is a general description of the country given to the two tribes and a half, by Moses. Israel must know their own, and keep to it; and may not, under pretence of their being God's peculiar people, encroach on their neighbours. Twice in this chapter it is noticed, that to the tribe of Levi Moses gave no inheritance: see Nu 18:20. Their maintenance must be brought out of all the tribes. The ministers of the Lord should show themselves indifferent about worldly interests, and the people should take care they want nothing suitable. And happy are those who have the Lord God of Israel for their inheritance, though little of this world falls to their lot. His providences will supply their wants, his consolations will support their souls, till they gain heavenly joy and everlasting pleasures.
