Matthew Poole and continuators on Joshua 17:5

5 And there fell ten portions to Manasseh, beside the land of Gilead, and Bashan, which were on the other side Jordan:

Either 1. Six portions for the six Sons, whereof one was Hepher; and because he had no Sons, his part was subdivided into five equal parts, for each of the Daughters: Or, 2. Ten Portions, five for the Sons, and five for the Daughters; for as for Hepher, both he and his Son Zelophehad was dead, and that without Sons, and therefore he had no Portion; but his Daughters had several Portions allotted to them.
