Deuteronomy 2:14

The days in which we came from Kadesh Barnea until we had come over the brook Zered were thirty-eight years, until all the generation of the men of war were consumed from the middle of the camp, as Yahweh swore to them.

And the space in which we came from Kadesh-barnea, until we were come over the brook Zered, was thirty and eight years; until all the generation of the men of war were wasted out from among the host, as the LORD sware unto them.
