Rahab showed her “faith” in her confession, Jos 2:9, Jos 2:11, “I know that Jehovah hath given you the land; Jehovah your God, is God in heaven above, and in earth beneath.”
the harlot - Her former life adds to the marvel of her repentance, faith, and preservation (Mat 21:31, Mat 21:32).
believed not - Greek, “were disobedient,” namely, to the will of God manifested by the miracles wrought in behalf of Israel (Jos 2:8-11).
received - in her house (Jos 2:1, Jos 2:4, Jos 2:6).
with peace - peaceably; so that they had nothing to fear in her house. Thus Paul, quoting the same examples (Heb 11:17, Heb 11:31) for the power of faith, as James (Jam 2:21, Jam 2:25; see on Jam 2:21; see on Jam 2:25) does for justification by works evidentially, shows that in maintaining justification by faith alone, he means not a dead faith, but “faith which worketh by love” (Gal 5:6).
