Deuteronomy 2:16-22

16So it came to pass, when all the men of war were consumed and dead from among the people, 17that Jehovah spake unto me, saying, 18Thou art this day to pass over Ar, the border of Moab: 19and when thou comest nigh over against the children of Ammon, vex them not, nor contend with them; for I will not give thee of the land of the children of Ammon for a possession; because I have given it unto the children of Lot for a possession. 20(That also is accounted a land of Rephaim: Rephaim dwelt therein aforetime; but the Ammonites call them Zamzummim, 21a people great, and many, and tall, as the Anakim; but Jehovah destroyed them before them; and they succeeded them, and dwelt in their stead; 22as he did for the children of Esau, that dwell in Seir, when he destroyed the Horites from before them; and they succeeded them, and dwelt in their stead even unto this day.
