Joshua 10:34

30 And the LORD also delivered that city and its king into the hand of Israel, and Joshua put all the people to the sword, leaving no survivors. And he did to the king of Libnah as he had done to the king of Jericho.

31 And Joshua and all Israel with him moved on from Libnah to Lachish. They laid siege to it and fought against it.

32 And the LORD delivered Lachish into the hand of Israel, and Joshua captured it on the second day. He put all the people to the sword, just as he had done to Libnah.

33 At that time Horam king of Gezer went to help Lachish, but Joshua struck him down along with his people, leaving no survivors.

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.
