Matthew Henry on Numbers 36:1-4

The heads of the tribe of Manasseh represent the evil which might follow, if the daughters of Zelophehad should marry into any other tribes. They sought to preserve the Divine appointment of inheritances, and that contests and quarrels should not rise among those who should come afterwards. It is the wisdom and duty of those who have estates in the world, to settle them, and to dispose of them, so that no strife and contention may arise. (Nu 36:5-12)
