Gilead: A Region East of the Jordan River Allotted to the Tribes of Reuben and Gad and the Half Tribe of Manasseh

Now the Reubenites and Gadites, who had very large herds and flocks, surveyed the lands of Jazer and Gilead, and they saw that the region was suitable for livestock. …

To the half-tribe of Manasseh I gave the rest of Gilead and all of Bashan, the kingdom of Og. (The entire region of Argob, the whole territory of Bashan, used to be called the land of the Rephaim.)

Then Moses went up from the plains of Moab to Mount Nebo, to the top of Pisgah, which faces Jericho. And the LORD showed him the whole land—from Gilead as far as Dan,

…from the Jordan eastward through all the land of Gilead (the region of Gad, Reuben, and Manasseh), and from Aroer by the Arnon Valley through Gilead to Bashan.
