[This] was the lot for the tribe of Manasseh; for he was the firstborn of Joseph. As for Machir the firstborn of Manasseh, the father of Gilead, because he was a man of war, therefore he had Gilead and Bashan.
The bearing of this on the distribution of the land is seen at once when it is remembered that Manasseh's DOUBLE PORTION (as was his right as the first-born) was already ONE-HALF expended in the settlement of Manasseh's first-born (who was Machir) who possessed Gilead and Bashan eastward of the Jordan.  In that light, how logical and necessary is the next declaration that, "the lot was for the rest of the children of Manasseh."  There were six of these "other male children" of Manasseh, the names of which are listed here.  The six cited here are actually GRANDSONS of Machir through Gilead  (Numbers 26:30-42).  Hepher was deceased, leaving only five "sons."
