Manasseh was itself but one half of the tribe of Joseph, and yet was divided and subdivided. 1. It was divided into two parts, one already settled on the other side Jordan, consisting of those who were the posterity of Machir, Jos 17:1.

The descent of this man is particularly given, to show the truth and reality of it, upon which his daughters made their request, and that granted and now claimed: and these are the names of his daughters, Mahlah, and Noah, Hoglah, Milcah...
Zelophehad - had no sons, but daughters - See this case considered at large in the notes on Num 27:1-7 (note); Num 36:1 (note), etc.
