Deuteronomy 3:14-18

Jair the son of Manasseh took all the region of Argob as far as the border of the Geshurites and the Maacathites, that is, Bashan, and named it after his own name: Havvoth-jair, as it is to this day.)

To Machir I gave Gilead.

To the Reubenites and the Gadites I gave from Gilead even as far as the Valley of Arnon, the middle of the valley as a border, and as far as the river Jabbok, the border of the sons of Ammon;

the Arabah also, with the Jordan as a border, from Chinnereth even as far as the sea of the Arabah, the Salt Sea, at the foot of the slopes of Pisgah on the east.

“Then I commanded you at that time, saying, ‘The Lord your God has given you this land to possess it; all you valiant men shall cross over armed ahead of your brothers, the sons of Israel.
