(Og king of Bashan was the last of the Rephaites. His bed was decorated with iron and was more than nine cubits long and four cubits wide. It is still in Rabbah of the Ammonites.) (NIV)
For only Og king of Bashan remained of the remnant of the [gigantic] Rephaim. Behold, his bedstead was of iron; is it not in Rabbah of the Ammonites? Nine cubits was its length and four cubits its breadth, using the cubit of a man [the forearm to the end of the middle finger]. (AMP)
For only Og king of Bashan remained of the remnant of giants; behold his bedstead was a bedstead of iron; is it not in Rabbath of the children of Ammon? nine cubits was the length thereof, and four cubits the breadth of it, after the cubit of a man. (KJV)
