Contradiction with Exodus 20:16
It contradicts by emphasizing the importance of not bearing false witness, while Rahab's actions in Joshua 2:6 involve deception.
Exodus 20:16: Thou shalt not bear false witness against thy neighbour.
Contradiction with Proverbs 12:22
It contrasts Rahab's lie since it states that lying lips are an abomination to the Lord.
Proverbs 12:22: Lying lips [are] abomination to the LORD: but they that deal truly [are] his delight.
Contradiction with James 2:25
It presents Rahab's actions as justified by faith, which can contradict with the negative view on deception.
James 2:25: Likewise also was not Rahab the harlot justified by works, when she had received the messengers, and had sent [them] out another way?
Contradiction with Revelation 21:8
It lists liars among those who face judgment, conflicting with Rahab's deceptive act in Joshua 2:6.
Revelation 21:8: But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.
Contradiction with Colossians 3:9
It advises against lying, which contradicts Rahab's falsehood in hiding the spies.
Colossians 3:9: Lie not one to another, seeing that ye have put off the old man with his deeds;
Paradox #1
Joshua 2:6 involves the story of Rahab hiding Israelite spies. A contradiction here is that Rahab lies to protect the spies, and lying is generally considered wrong in biblical teachings. However, her actions are portrayed positively because they helped God's people. This creates an inconsistency between the act of lying and the positive outcome it achieves in this context.
