1. Joshua helped his people spiritually (18:1-10)
Seven tribes were slow to obey God and possess their land. Joshua helped them overcome. First, he rebuked them with the truth. He directed them to send three men from each tribe to survey their allotment and write a description of it. Then Joshua cast lots for them at the tabernacle. In doing so, they allowed God to assign tribes to certain lands. Joshua acted as a good shepherd.
2. God's wisdom in the allotments (18:11-19:51)
The allotments were clearly described with the boundaries and the cities listed. This is God's wisdom. If each tribe had their own territory, then each would be responsible for it. They could not delay in clearing the land. Each region would have ownership, a clear identity and unity. God helps us overcome procrastination so we can move ahead.
