Joshua 6:17, 25

And the city shall be devoted, even it and all that is therein, to Jehovah: only Rahab the harlot shall live, she and all that are with her in the house, because she hid the messengers that we sent.

But Rahab the harlot, and her father’s household, and all that she had, did Joshua save alive; and she dwelt in the midst of Israel unto this day, because she hid the messengers, whom Joshua sent to spy out Jericho.
