Deuteronomy 3:11-12

(For Og, king of Bashan, was the last of all the Rephaim; his bed was made of iron; is it not in Rabbah, in the land of the children of Ammon? It was nine cubits long and four cubits wide, measured by the common cubit.) And this land which we took at that time, from Aroer by the valley of the Arnon, and half the hill-country of Gilead with its towns, I gave to the Reubenites and the Gadites.
