How big was king Og's bed?


Nine cubits long and four cubits wide

(13.5 feet long and 6 feet wide)
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. Deuteronomy 3:11
