And Joshua saved Rahab the harlot alive. — “By faith the harlot Rahab perished not with them that believed not” (Hebrews 11:31). And so Jesus said to her who had ministered to Him in the house of Simon the Pharisee, “Thy sins are forgiven;” and again, “Thy faith hath saved thee: go in peace” Luke 7:48; Luke 7:50). “Likewise also was not Rahab the harlot justified by works?” (James 2:25).
And she dwelleth in Israel even unto this day. — “Salmon begat Booz of Rachab” seems certainly to refer to her (Matthew 1:5), though why she is called Rachab in that place is not obvious. Rachab is not the usual form of the word, either in the LXX. or in the other passages of the Greek text where she is named. It is not simply a variation in the English spelling, but a difference in the original Greek.
