'Four' in the Bible

(For only Og king of Bashan remained of the remnant of the Rephaim; behold, his bedstead was a bedstead of iron; is it not in Rabbah of the children of Ammon? nine cubits was the length thereof, and four cubits the breadth of it, after the cubit of a man.)

Thou shalt make thee fringes upon the four borders of thy vesture, wherewith thou coverest thyself.
