Darby Translation

²² as he did to the children of Esau, who dwelt in Seir, from before whom he destroyed the Horites; and they dispossessed them, and dwelt in their stead, even to this day.

²³ And the Avvites who dwelt in the hamlets as far as Gazah—the Caphtorim, who came out of Caphtor, destroyed them, and dwelt in their stead.)

²⁴ Rise up, take your journey, and pass over the river Arnon. Behold, I have given into thy hand Sihon the king of Heshbon, the Amorite, and his land: begin, take possession, and engage with him in battle.
