1 Chronicles 4:39-43

39and they traveled to the region of Gerar, in the east part of the valley, seeking pastureland for their flocks.

40They found lush pastures there, and the land was spacious, quiet, and peaceful. Some of Ham’s descendants had been living in that region.

41But during the reign of King Hezekiah of Judah, these leaders of Simeon invaded the region and completely destroyed the homes of the descendants of Ham and of the Meunites. No trace of them remains today. They killed everyone who lived there and took the land for themselves, because they wanted its good pastureland for their flocks.

42Five hundred of these invaders from the tribe of Simeon went to Mount Seir, led by Pelatiah, Neariah, Rephaiah, and Uzziel—all sons of Ishi.

43They destroyed the few Amalekites who had survived, and they have lived there ever since.
