'Prostitute' in the Bible

Joshua son of Nun sent two spies out from Shittim secretly and instructed them: "Find out what you can about the land, especially Jericho." They stopped at the house of a prostitute named Rahab and spent the night there.

The city and all that is in it must be set apart for the Lord, except for Rahab the prostitute and all who are with her in her house, because she hid the spies we sent.

Yet Joshua spared Rahab the prostitute, her father's family, and all who belonged to her. She lives in Israel to this very day because she hid the messengers Joshua sent to spy on Jericho.
