Moses told them, “If the tribes of Gad and Reuben get ready for battle in the Lord’s presence and cross the Jordan River with you and you conquer the land, give them Gilead as their own property.
Then we’ll be ready ⌞to march⌟ in battle formation ahead of the other Israelites until we have brought them to their land. Meanwhile our families will live in walled cities, safe from the other people who live here.
The Lord’s servant Moses and the people of Israel defeated them. Then he gave their land as a possession to the tribes of Reuben and Gad and half of the tribe of Manasseh.
Levi’s tribe has no separate region among you, because their inheritance is to serve the Lord as priests. The tribes of Gad and Reuben and half of the tribe of Manasseh have received the inheritance that the Lord’s servant Moses gave them on the east side of the Jordan River.”
So the tribes of Reuben and Gad and half of the tribe of Manasseh left the rest of the Israelites at Shiloh in Canaan. They returned to Gilead. This was their own possession which they had captured as the Lord had instructed them through Moses.
