There is nothing particularly significant to note in the allotment given to Zebulun. Their territory was in the north and it is hard to know exactly where each of the locations mentioned were. Two of their cities do not appear elsewhere in the Bible. The Bethlehem found in Zebulun is not the same as the Bethlehem in Judah, instead it is the site where Ibzan the judge was buried (Judges 12:8–10).1
10 The third lot came up for the people of Zebulun, according to their clans. And the territory of their inheritance reached as far as Sarid.
