'Length' in the Bible

Now the {length of time} that we had traveled from Kadesh Barnea until [the time when] we crossed the wadi of Zered [was] thirty-eight years, until the perishing of all of that generation; [that is], the men of war from the midst of the camp as Yahweh had sworn to them.

(For only Og, king of Bashan, was left from the remnant of the Rephaim. Indeed, his bedstead--it [was] a bedstead of iron. It is in Rabbah of the {Ammonites}. Nine cubits [is] its length, and four cubits [is] its width according to the cubit of a man.)

by loving Yahweh your God by listening to his voice and by clinging to him, for he [is] your life and the length of your days [in order for you] to live on the land that Yahweh swore to your ancestors, to Abraham, to Isaac, and to Jacob, to give to them."
