Joshua 6:24-25

24But they burned the city and all that was in it with fire. Only the silver and gold, and the vessels of bronze and iron, they put into the treasury of the house of the Lord.

25And Joshua spared Rahab the harlot, her father’s household, and all that she had. So she dwells in Israel to this day, because she hid the messengers whom Joshua sent to spy out Jericho.
