Joshua 6:17
The city and all that is in it are to be devoted to the LORD. Only Rahab the prostitute and all who are with her in her house shall be spared, because she hid the spies we sent.
James 2:25
In the same way, was not even Rahab the prostitute considered righteous for what she did when she gave lodging to the spies and sent them off in a different direction?
