Deuteronomy 3:10-11
3:10 all the cities of the plateau, all of Gilead and Bashan as far as Salecah and Edrei, cities of the kingdom of Og in Bashan.
3:11 Only King Og of Bashan was left of the remaining Rephaites. (It is noteworthy that his sarcophagus was made of iron. Does it not, indeed, still remain in Rabbath of the Ammonites? It is thirteen and a half feet long and six feet wide according to standard measure.)
