Moses is recounting the allocation of land to the tribes of Reuben and Gad. These tribes were given territory on the east side of the Jordan River, specifically north of Aroer by the Arnon Gorge, which included half of the hill country of Gilead and its towns. This area was known for its fertility and suitability for livestock, which was important for these tribes. The allocation of this land was part of the broader division among the Israelites as they prepared to enter the Promised Land.
This verse underscores the importance of God's provision and the fulfillment of His promises. It reflects the careful planning and organization required to establish a community in a new land. The division of land also illustrates the importance of shared responsibility and cooperation among the tribes. As the Israelites prepared to settle in the Promised Land, they were reminded of their collective journey and the need to work together to fulfill God's plan. This passage encourages believers to trust in God's provision and to value community and cooperation in their own faith journeys.
