Joshua 17:1

1 A part of the land west of the Jordan was assigned to some of the families descended from Joseph's older son Manasseh. Machir, the father of Gilead, was Manasseh's oldest son and a military hero, so Gilead and Bashan, east of the Jordan, were assigned to him.

Joshua 17:1 Meaning and Commentary

Joshua 17:1

There was also a lot for the tribe of Manasseh
As well as for the tribe of Ephraim:

for he [was] the firstborn of Joseph;
and therefore ought to have his part and share in the lot of the children of Joseph, though Ephraim was preferred before him in the blessing of Jacob. Some think this is given as a reason why he had a double portion, one on the other side Jordan, and another in the land of Canaan:

[to wit], for Machir, the firstborn of Manasseh, the father of Gilead;
who was the only son of Manasseh, and so through him, and by his son Gilead, the whole tribe sprung from that patriarch: and

because he was a man of war, therefore he had Gilead and Bashan;
which were given to his posterity by Moses, and lay on the other side Jordan, see ( Deuteronomy 3:13 Deuteronomy 3:15 ) . This Machir very likely had shown his warlike disposition and courage in Egypt, and had fought under the kings there against the common enemy of that country; for it is highly probable he was dead before the children of Israel came out from thence, but the same warlike spirit continued in his posterity; they had their part assigned them on the other side Jordan, to defend that country, while the tribes of Reuben and Gad attended to the care of their flocks and herds.

Joshua 17:1 In-Context

1 A part of the land west of the Jordan was assigned to some of the families descended from Joseph's older son Manasseh. Machir, the father of Gilead, was Manasseh's oldest son and a military hero, so Gilead and Bashan, east of the Jordan, were assigned to him.
2 Land west of the Jordan was assigned to the rest of the families of Manasseh: Abiezer, Helek, Asriel, Shechem, Hepher, and Shemida. These were male descendants of Manasseh son of Joseph, and they were heads of families.
3 Zelophehad, son of Hepher, son of Gilead, son of Machir, son of Manasseh, did not have any sons, but only daughters. Their names were Mahlah, Noah, Hoglah, Milcah, and Tirzah.
4 They went to Eleazar the priest and to Joshua son of Nun and to the leaders, and said, "The Lord commanded Moses to give us, as well as our male relatives, a part of the land to possess." So, as the Lord had commanded, they were given land along with their male relatives.
5 This is why Manasseh received ten shares in addition to Gilead and Bashan on the east side of the Jordan,
