Joshua 22:6-10

So Joshua blessed them and sent them away, and they went to their tents.

Now to the one half-tribe of Manasseh Moses had given a possession in Bashan, but to the other half Joshua gave a possession among their brothers westward beyond the Jordan. So when Joshua sent them away to their tents, he also blessed them,

and said to them, “Return to your tents with great riches and with very many livestock, with silver, gold, bronze, iron, and with very many clothes; divide the spoils of your enemies with your brothers.”

So the sons of Reuben, the sons of Gad, and the half-tribe of Manasseh returned home, leaving the sons of Israel at Shiloh, which is in the land of Canaan, to go to the land of Gilead, to the land of their possession in which they had settled, in accordance with the command of the Lord through Moses.
