Numbers 36:1

We have here the humble address which the heads of the tribe of Manasseh made to Moses and the princes, on occasion of the order lately made concerning the daughters of Zelophehad. The family they belonged to was part of that half of the tribe of Manasseh which we yet to have their lot within Jordan, not that half that was already settled; and yet they speak of the land of their possession, and the inheritance of their fathers, with as great assurance as if they had it already in their hands, knowing whom they had trusted. In their appeal observe, 1. They fairly recite the former order made in this case, and do not move to have that set aside, but are very willing to acquiesce in it (Num 36:2): The Lord commanded to give the inheritance of Zelophehad to his daughters; and they are very well pleased that it should be so, none of them knowing but that hereafter it might be the case of their own families, and then their daughters would have the benefit of this law. 2. They represent the inconvenience which might, possibly, follow hereupon, if the daughters of Zelophehad should see cause to marry into any other tribes, Num 36:3.
