Joshua 10:38

34 So Joshua moved on from Lachish to Eglon, and all Israel with him. They laid siege to it and fought against it.

35 That day they captured Eglon and put it to the sword, and Joshua devoted to destruction everyone in the city, just as he had done to Lachish.

36 Then Joshua and all Israel with him went up from Eglon to Hebron and fought against it.

37 They 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.

38 Finally Joshua and all Israel with him turned toward Debir and fought against it.

39 And 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.

40 So Joshua conquered the whole region—the hill country, the Negev, the foothills, and the slopes, together with all their kings—leaving no survivors. He devoted to destruction everything that breathed, just as the LORD, the God of Israel, had commanded.

41 Joshua conquered the area from Kadesh-barnea to Gaza, and the whole region of Goshen as far as Gibeon.

42 And because the LORD, the God of Israel, fought for Israel, Joshua captured all these kings and their land in one campaign.
