I'd like to make a suggestion that while you're reading these historical books that you take time to consult a Bible atlas and try to locate some of the places mentioned in the Scriptures. It will give you a better perspective on what you're reading and it will also help you to see that these historical events happened in very real, historical places!
Joshua 16 - This short chapter speaks of the land allotted to the tribe of Ephraim. They would be located in the strategic middle of the nation and the result would be their strong influence on the rest of the land, especially the northern tribes.
Joshua 17 - Remember the tribe of Manasseh was divided long before the conquering of Canaan. Back in Numbers the people of half of the tribe of Manasseh wanted their inheritance to be on the east side of the Jordan River. This chapter in Joshua now speaks of the other half of that tribe and their allotment of land being just north of Ephraim.
Joshua 18 - Please note Joshua's searching question in verse 3, "How long will you neglect to go and possess the land which the Lord God of your fathers has given you?" These seven remaining tribes needed this scolding from their leader. And we need that too! How many of God's blessings available to you are you yet to "claim" as your own?!
