Deuteronomy 2:19

And when you approach the territory of the people of Ammon , do not harass them or contend with them, for I will not give you any of the land of the people of Ammon as a possession , because I have given it to the sons of Lot for a possession .

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.”

And when thou comest nigh over against the children of Ammon, distress them not, nor meddle with them: for I will not give thee of the land of the children of Ammon any possession; because I have given it unto the children of Lot for a possession.
