Y'hoshua (Jos) 2:3-7

The king of Yericho sent a message to Rachav, “Bring out the men who came to you and are staying in your house, because they have come to reconnoiter all the land.” However, the woman, after taking the two men and hiding them, replied, “Yes, the men did come to me; but I didn’t know where they had come from. The men left around the time when they shut the gate, when it was dark. Where they went I don’t know; but if you chase after them quickly, you will overtake them.” Actually she had brought them up to the roof and hidden them under some stalks of flax she had spread out there. The men pursued them all the way to the fords at the Yarden; as soon as the pursuit party had left, the gate was shut.
