1 Chronicles 4:39-43

39and they went to the outskirts of Gedor to the east of the valley in search of pasture for their flocks.

40They found rich, good pasture, and the land was spacious, peaceful and quiet. Some Hamites had lived there formerly.

41The men whose names were listed came in the days of Hezekiah king of Judah. They attacked the Hamites in their dwellings and also the Meunites who were there and completely destroyed them, as is evident to this day. Then they settled in their place, because there was pasture for their flocks.

42And five hundred of these Simeonites, led by Pelatiah, Neariah, Rephaiah and Uzziel, the sons of Ishi, invaded the hill country of Seir.

43They killed the remaining Amalekites who had escaped, and they have lived there to this day.
