1 Chronicles 4:41-43

41And these written by name came in the days of Hezekiah king of Judah, and smote their tents, and the habitations that were found there, and destroyed them utterly to this day, and dwelt in their stead: because there was pasture there for their flocks. 42And some of them, even of the sons of Simeon, five hundred men, went to mount Seir, having for their captains Pelatiah, and Neariah, and Rephaiah, and Uzziel, the sons of Ishi. 43And they smote the rest of the Amalekites that had escaped, and have dwelt there to this day.
