'Length' 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.)

to love Jehovah thy God, to obey his voice, and to cleave unto him; for he is thy life, and the length of thy days; that thou mayest dwell in the land which Jehovah sware unto thy fathers, to Abraham, to Isaac, and to Jacob, to give them.
