Deuteronômio 2:19

19 When 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."

19 And when you come near the land of the children of Ammon, give them no cause of trouble and do not make war on them, for I will not give you any of the land of the children of Ammon for your heritage: because I have given it to the children of Lot.
