Deuteronomy 2:7; Deuteronomy 2:14

7 For the LORD your God has blessed you in all the work of your hands. He knows your going through this great wilderness. These forty years the LORD your God has been with you. You have lacked nothing."'

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.
