Deuteronomy 2:20-22

New Revised Standard Version Catholic Edition

²⁰ (It also is usually reckoned as a land of Rephaim. Rephaim formerly inhabited it, though the Ammonites call them Zamzummim, ²¹ a strong and numerous people, as tall as the Anakim. But the Lord destroyed them from before the Ammonites so that they could dispossess them and settle in their place. ²² He did the same for the descendants of Esau, who live in Seir, by destroying the Horim before them so that they could dispossess them and settle in their place even to this day.
