'Length' in the Bible

(For only Og king of Bashan was left of the remnant of the Rephaim. Behold, his bedstead was an iron bedstead; it is in Rabbah of the sons of Ammon. Its length was nine cubits and its width four cubits by ordinary cubit.)

by loving the Lord your God, by obeying His voice, and by holding fast to Him; for this is your life and the length of your days, that you may live in the land which the Lord swore to your fathers, to Abraham, Isaac, and Jacob, to give them.”
