The second half of Joshua 1 (Joshua 1:10–18) testifies to the unity of God’s people. A new leader has been appointed, he issues commands, and all the people obey. They recognize him as God’s servant, they unite in service under him.

The special mention of the Reubenites, Gadites and the half-tribe of Manasseh should also be understood in the context of unity. Even if these tribes will live in the land to the east of the Jordan River, they still commit themselves to help with the fighting. The well being of their brothers and sisters is also a concern to them.

The focus of their service is on helping believers to take possession of the land. That is what these three tribes are being called on to do together with the rest of God’s people. They must help their brothers and sisters take possession of the land.

In our context as Christians, we must help one another to take possession of heaven. Encourage each other to live in the light of God’s promises, to make decisions based on biblical principles and not fear. That’s why it is so important for us to keep meeting together (Hebrews 10:25; Psalm 122:1–9). How else are we going to encourage one another?
