Rahab
Rahab’s story is told in Joshua 2 and Joshua 6.
Any women keeping an inn and offering lodging could be considered a prostitute. Men staying in such an inn would not draw attention. Both Josephus (Ant.Jews.5.1.2) and an Aramaic translation of the Old Testament entitled Targum Jonathan describe Rahab as an innkeeper. She also appears to be in the business of manufacturing linen and engaged in the art of dyeing. The truth is most adultery mentioned in the Bible is not sexual. but national. http://www.preparingyou.com/wiki/Adultery
