Joshua 10:36-39

36Then Joshua and all Israel with him went up from Eglon to Hebron and fought against it. 37They captured it and put to the sword its king, all its villages, and all the people. Joshua left no survivors, just as he had done at Eglon; he devoted to destruction Hebron and everyone in it.

38Finally Joshua and all Israel with him turned toward Debir and fought against it. 39And they captured Debir, its king, and all its villages. They put them to the sword and devoted to destruction everyone in the city, leaving no survivors. Joshua did to Debir and its king as he had done to Hebron and as he had done to Libnah and its king.
