Joshua 13:31

And half Gilead
The other half not given to the Gadites, who had that half of it which Sihon possessed, and the tribe of Manasseh that half of it which Og possessed, see ( Deuteronomy 3:12 Deuteronomy 3:13 ) ;

and Ashtaroth, and Edrei, cities of the kingdom of Og in Bashan;
which are particularly mentioned, because royal cities, ( Joshua 13:10 ) ; see ( Deuteronomy 1:4 ) ;

[were pertaining] unto the children of Machir the son of Manasseh;
and who was his only son; however, to his posterity only was this inheritance given, though not to them all:

[even] to one half of the children of Machir, by their families;
which seems to confirm it that Manasseh had no other son, since his whole posterity, both the half tribe on the other side, as well as that in the land of Canaan, were denominated from him; though he seems to have had another son, who perhaps died without issue, ( 1 Chronicles 7:14 ) .
