The harlot who secreted the spies that Joshua sent into the land. She had heard of the wonders of God in delivering Israel out of Egypt, and she was aware of the fear that had fallen on the inhabitants. In faith she risked her life in hiding the spies. Her stratagem was successful, and she made an agreement with the spies, that if she did not betray them, her life and the life of her family should be saved when the city was taken. This was only to be binding on them if she brought all into her house, under the token of the scarlet line, hung out at the window from which the spies were let down, the house being built upon the wall. Joshua was careful that the compact should be respected, and she and her relatives were saved (Josh. 2:1-22; Josh. 6:17-25).
Rahab was a traitor to her country, and lied to the king; but it was to throw herself under the protection of the God of Israel. Her falsehood is not commended; her faith is (Heb. 11:31); and her works justified her—before men (Jas. 2:25). That the RACHAB of Matthew 1:5 is the same as Rahab is evidenced by the article; it was the Rachab mentioned in the Old Testament (the Greek language having no letter H, a CH [X] is substituted). That such women as Rahab and Thamar should be mentioned in the genealogy of the Lord Jesus shows the divine origin of the list, for man would probably have omitted these names. Their insertion exalts the grace that superabounds over all sin.
