The harlot's house Which, together with the wall upon which it leaned, was left standing, by a special favour of God to her. Left them without the camp of Israel Till they were cleansed from the impurities of their Gentile state, and instructed in the Jewish religion, and solemnly admitted into that church, for which Rahab's good counsel and example had doubtless prepared them. Joshua saved Rahab alive For that general command to root out the Canaanites seems to have had some exceptions, in case any of them had sincerely and seasonably cast off their idolatry and wickedness, submitted to the Israelites, and become members of the church of God. She dwelleth in Israel unto this day This shows that the book of Joshua was written while Rahab was alive.
Joshua 6:22-25
22 But Joshua had said unto the two men that had spied out the country, Go into the harlot's house, and bring out thence the woman, and all that she hath, as ye sware unto her.
23 And the young men that were spies went in, and brought out Rahab, and her father, and her mother, and her brethren, and all that she had; and they brought out all her kindred,h and left them without the camp of Israel.
24 And they burnt the city with fire, and all that was therein: only the silver, and the gold, and the vessels of brass and of iron, they put into the treasury of the house of the LORD.
25 And Joshua saved Rahab the harlot alive, and her father's household, and all that she had; and she dwelleth in Israel even unto this day; because she hid the messengers, which Joshua sent to spy out Jericho.
