Deuteronomy 2:13-19

13And the LORD said, “Now get up and cross the Zered Valley.” So we crossed the valley. 14Thirty-eight years passed from the time we left Kadesh Barnea until we crossed the Zered Valley. By then, that entire generation of fighting men had perished from the camp, as the LORD had sworn to them.

15The LORD ’s hand was against them until he had completely eliminated them from the camp. 16Now when the last of these fighting men among the people had died, 17the LORD said to me, 18“Today you are to pass by the region of Moab at Ar.

19When you come to the Ammonites, do not harass them or provoke them to war, for I will not give you possession of any land belonging to the Ammonites. I have given it as a possession to the descendants of Lot.”
