'Length' in the Bible

for only Og king of Bashan had been left of the remnant of the Rephaim; lo, his bedstead is a bedstead of iron; is it not in Rabbath of the sons of Ammon? nine cubits its length, and four cubits its breadth, by the cubit of a man.

to love Jehovah thy God, to hearken to His voice, and to cleave to Him (for He is thy life, and the length of thy days), to dwell on the ground which Jehovah hath sworn to thy fathers, to Abraham, to Isaac, and to Jacob, to give to them.'
