Guesses have been made that she had been a concubine, such as Hagar and Zilpah had been, but that in Jericho she was a reputable woman identified with a respectable business.
The Bible, however, makes no attempt to smooth over the unpleasant fact that Rahab had been a harlot.
These were men of God, not idolaters, bent on one mission, namely, the overthrow of the enemies of His people, and brilliantly she planned their protection and escape.
The flax that she spread on her roof and the scarlet cord she used as a sign indicated that Rahab manufactured linen and also dyed it.
Like many a young girl today perhaps she found the restrictions of her respectable home too irk-some.
She wanted a freer life, a life of thrill and excitement, away from the drab monotony of the home giving her birth and protection.
Evidently Rahab had her own house and lived apart from her parents and family.
Although she never lost her concern for her dear ones, perhaps she was treated as a moral leper.
The gratitude Salmon felt for Rahab ripened into love, and when grace erased her former life of shame he made her his wife.
Some of the ancient Jewish fathers who held her in high reputation reckoned that she was the wife of Joshua himself, but in the royal genealogy of Jesus, Rahab is referred to as being the wife of Salmon, one of the two spies she sheltered.
In turn, she became the mother of Boaz, who married Ruth from whose son, Obed, Jesse the father of David came, through whose line Jesus was born (Matthew 1:5, where the reads, “Salmon begat Boaz of Rahab”—not Rachab).
We are told that prostitution was not regarded with the same horror then, as now, but the Bible with one voice speaks of harlotry with moral revulsion and social ostracism.
Rahab’s house was built against the town wall with the roof almost level with the ramparts, and with a stairway leading up to a flat roof that appears to be a continuation of the wall.Thus, the people of Jericho knew all about the men who entered and left such a disreputable house.
