Joshua 2:1-3

Joshua the son of Nun sent two men as scouts secretly from Shittim, saying, “Go, view the land, especially Jericho [the walled city].” So they went and came to the house of a prostitute named Rahab, and lodged there. Now the king of Jericho was told, “Behold, men from the sons of Israel have come here tonight to spy and search out the land.” So the king of Jericho sent word to Rahab, saying, “Bring out the men who have come to you, who entered your house, because they have come [as spies] to search out all the land.”
