But Zelophehad, the son of Hepher, the son of Gilead, the son of Machir, the son of Manasseh, had no sons, but daughters: and these are the names of his daughters, Mahlah, and Noah, Hoglah, Milcah, and Tirzah.
Manasseh was Joseph's firstborn, yet Jacob preferred Ephraim; so he received a double portion, half already settled beyond Jordan under Machir, a man of war who won Gilead and Bashan through valor. The other half, on this side Jordan, was divided among ten families descended from Gilead's six sons, though one line failed and passed to five daughters of Zelophehad, each inheriting her share.
