The Lord gave Lachish into the hand of Israel. They captured it on the second day and struck all who lived in it with the edge of the sword, just as they had done to Libnah.
and when the Lord your God delivers them before you and you strike them down, then you must utterly destroy them. You shall make no covenant with them nor show mercy to them.
Joshua took Makkedah that day and struck it and its king with the edge of the sword. He destroyed it and all life within it. He did not leave any survivors. He did to the king of Makkedah just as he did to the king of Jericho.
Joshua captured all these kings and their towns. He struck with the edge of the sword, destroying them, as Moses the servant of the Lord had commanded.
