And it came to pass, when Joshua and the children of Israel had made an end of slaying them with a very great slaughter, till they were consumed, and the remnant which remained of them had entered into the fortified cities,
So Joshua and the Israelites continued to inflict a terrible slaughter until they had finished them off, and the remaining survivors retreated to the fortified cities.
