Joshua 6:24-25

24Then 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.

25So 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.
