Joshua 2:1-6

Then Joshua, son of Nun, secretly sent out two spies from Shittim. “Go and explore the land, especially around Jericho,” he told them. So they went, and stayed at the house of woman named Rahab, a prostitute. There they spent the night. But the king of Jericho was told, “Look, some Israelites have come here this evening to spy out the land.” So the king of Jericho sent orders to Rahab, telling her, “Hand over the men who came to visit you and stay in your house, for they've come to spy out our whole country.” The woman had taken the two men and had hidden them. She told the king's messengers, “Yes, it's true—the men did come to visit me, but I didn't know where they were from. They left at sundown, just as the city gate was closing. I've no idea where they went. If you're quick, you can chase after them and maybe catch up with them.” (She had taken them up to the roof and hidden them under some bundles of flax that she had lying there.)
