Charles Ellicott Commentary Joshua 19:17

"The fourth lot came out for Issachar, even for the children of Issachar according to their families." — Joshua 19:17 (ASV)

The fourth lot ... to Issachar. — These two tribes were located next to the house of Joseph on the north. It should be remembered that Issachar and Zebulun had been associated with Judah to form the same camp and division of the army in the wilderness. This association, lasting forty years, must have created many ties between these two tribes and their leader Judah. It was no ordinary wisdom that placed the descendants of Rachel (Ephraim, Benjamin, and Manasseh) between Judah on the south and Judah’s two associates on the north—to cement the union of all Israel, and as far as possible to prevent discord.

With regard to Judah and Zebulun, it is noticeable that we find their union reproduced in the earthly history of our Lord. Mary, who was of the house of David, and Joseph of the same lineage, are found dwelling in Nazareth, in the tribe of Zebulun. Thus the north and the south alike had “part in David,” and inheritance in David’s Son. There is a Bethlehem (Joshua 19:15) in Zebulun as well as in Judah. The name is not found in any other tribe.
