Joshua 10:18-20

New King James Version

¹⁸ So Joshua said, “Roll large stones against the mouth of the cave, and set men by it to guard them. ¹⁹ And do not stay there yourselves, but pursue your enemies, and attack their rear guard. Do not allow them to enter their cities, for the Lord your God has delivered them into your hand.” ²⁰ Then it happened, while Joshua and the children of Israel made an end of slaying them with a very great slaughter, till they had finished, that those who escaped entered fortified cities.
