And Moses gave unto them, even to the children of Gad and to the children of Reuben and unto half the tribe of Manasseh, the son of Joseph, this tribe thus being recognized as having equal claims with the other two, the kingdom of Sihon, king of the Amorites, and the kingdom of Og, king of Bashan, the land, with the cities thereof in the coasts (boundaries), even the cities of the country round about, the entire country with its cities and the cultivated land in the neighborhood of the cities.
