Deuteronomy 2:14; Deuteronomy 2:15

14 And the time from our leaving Kadesh-barnea until we crossed the brook Zered was thirty-eight years, until the entire generation, that is, the men of war, had perished from the camp, as the LORD had sworn to them.

15 For indeed the hand of the LORD was against them, to destroy them from the camp, until they had perished.
