9 Then the Lord said to me, “Do not harass Moab and provoke them to war, for I will not give you any of their land as your territory. This is because I have given Ar to the descendants of Lot as their possession. 10 (The Emites used to live there, a people as powerful, numerous, and tall as the Anakites. 11 These people, as well as the Anakites, are also considered Rephaites; the Moabites call them Emites. 12 Previously the Horites lived in Seir, but the descendants of Esau dispossessed and destroyed them and settled in their place, just as Israel did to the land it came to possess, the land the Lord gave them.)

Notes and References
"... Proverbs 2:18 warns of the woman whose house sinks down to death and her course to the rephaim; Proverbs 9:18 and 21:16 warn that men who stray will dwell with the rephaim. They are the company of the dead trembling in their graves, who cannot rise from the land of oblivion, or the ghosts who will indeed rise. The rephaim in Deuteronomy 2:11, 20 and 3:11-13, in contrast, are immense people as tall as the Anakites, as evidenced by the enormous iron bed of the king, and in several texts the term is used as a place name as well. It is surely no coincidence that the term refers to both a physically large people and the dead: once again, the picture is reminiscent of giant Near Eastern deities ..."
