Rahab the harlot lied to protect Israelite spies by telling the King of Jericho's men that the spies had already left the city when they were actually hiding on her roof. Some argue Rahab's lie was justified given the situation, while others say no lie is justified according to scripture. Rahab is praised in the Bible for protecting the spies, and went on to be included in Jesus' lineage, showing how God can forgive and use anyone. The document discusses whether lying is ever justified and what the Bible says about truth and lying.
