Joshua 6:21-25

Then they utterly destroyed everything that was in the city, both man and woman, young and old, and ox and sheep and donkey, with the edge of the sword. But Joshua said to the two men who had spied out the land, “Go into the prostitute’s house and bring the woman and all that she has out of there, as you have sworn to her.” So the young men, the spies, went in and brought out Rahab and her father and her mother and her brothers and everything that she had; they also brought out all her relatives and allowed them to stay outside the camp of Israel [at Gilgal during the time required for ceremonial cleansing]. [Num 31:19] Then they completely burned the city and everything that was in it. They put only the silver and the gold, and the articles of bronze and of iron, into the treasury of the house (tabernacle) of the LORD. So Joshua spared Rahab the prostitute, with her father’s household and everything that she had; and she has lived among Israel to this day, because she hid the messengers (scouts) whom Joshua sent to spy out Jericho.
