8With him the Reubenites and the Gadites received their inheritance, which Moses gave them, beyond the Jordan eastward, even as Moses the servant of Yahweh gave them: 9from Aroer, that is on the edge of the valley of the Arnon, and the city that is in the middle of the valley, and all the plain of Medeba to Dibon; 10and all the cities of Sihon king of the Amorites, who reigned in Heshbon, to the border of the children of Ammon; 11and Gilead, and the border of the Geshurites and Maacathites, and all Mount Hermon, and all Bashan to Salecah; 12all the kingdom of Og in Bashan, who reigned in Ashtaroth and in Edrei (who was left of the remnant of the Rephaim); for Moses attacked these, and drove them out.
