Salmon begat Booz (Boaz, Revised Version) of Rachab (Rahab, Revised Version). That this was Rahab of Jericho has been generally received, and it is clear from the narrative in Joshua 2:11, where Rahab declares, "The Lord your God, he is God in heaven above, and on earth beneath," that, whatever this woman's previous life and character may have been, she was then not unlikely to join herself to the Israelites.
Moreover, her great services rendered to the spies, and the conspicuous way in which she and her house were singled out for preservation from all the rest of the city, may have marked her as not unfit to become the wife of a chief man in Israel.

Some also say that she was made a proselyte, and was married to Joshua—a tradition followed, as it seems, in the Midrash 'Koh.
