Joshua 2:4-6

And the woman took the two men, and hid them; and she said, Yea, the men came unto me, but I knew not whence they were: and it came to pass about the time of the shutting of the gate, when it was dark, that the men went out; whither the men went I know not: pursue after them quickly; for ye will overtake them. But she had brought them up to the roof, and hid them with the stalks of flax, which she had laid in order upon the roof.
