Deuteronomy 2:16-23 - Journey Past Ammon
16 And as soon as all the men of war were consumed and dead from among the people, 17 then the LORD spake unto me, saying, 18 'Thou shalt go through Ar, the coast of Moab this day, 19 and shalt come nigh unto the children of Ammon: see that thou vex them not, nor yet provoke them. For I will not give thee of the land of the children of Ammon to possess; because I have given it unto the children of Lot to possess.'
20 That also was taken for a land of Giants - and Giants dwelt therein in old time, and the Ammonites called them Zamzummims: 21 a people that was great, many and tall, as the Anakims. But the LORD destroyed them before the Ammonites, and they cast them out and they dwelt there in their stead: 22 as he did for the children of Esau which dwell in Seir; even as he destroyed the Horites before them, and they cast them out and dwell in their stead unto this day. 23 And the Avims which dwelt in Hazerim even unto Gaza, the Caphthorims which came out of Caphthor destroyed them and dwelt in their rooms.
