1. God solved a dilemma (1-42)
The Levites were not allotted territory. According to a prophecy given through Jacob, Levi's descendants would be scattered (Gen 49:7) because of the slaughter of the Shechemites. Yet, they were blessed by Moses (Ex 32:28-29). Moses commanded that they be given towns (Num 35:2-3). How can God fulfill all of these factors? He gave them a priestly mission; scattering them in towns. Now the Levites were blessed, provided for, and made a blessing to the entire nation. The judgment and the mercy of God meet together. It is revealed in God's treatment of the Levites.
2. God fulfilled all of his promises (43-45)
The nation was settled. There was a time of rest from war. Fulfilling these promises took time. But the Lord works in his own time, not on our timetable. He is our faithful, sovereign Lord. We can trust him.
