Deuteronomy 3:10-11
10 We took all the towns on the plateau, and all Gilead, and all Bashan as far as Salecah and Edrei, towns of Og’s kingdom in Bashan.
11 (Only Og king of Bashan was left of the remnant of the Rephaites. His bed was made of iron and was more than thirteen feet long and six feet wide. It is still in Rabbah of the Ammonites.)
