Joshua 2:2-6

And it was told the king of Jericho, saying, Behold, there came men in hither to night of the children of Israel to search out the country.

And the king of Jericho sent unto Rahab, saying, Bring forth the men that are come to thee, which are entered into thine house: for they be come to search out all the country.

And the woman took the two men, and hid them, and said thus, There came men unto me, but I wist not whence they were:

And it came to pass about the time of shutting of the gate, when it was dark, that the men went out: whither the men went I wot not: pursue after them quickly; for ye shall overtake them.

But she had brought them up to the roof of the house, and hid them with the stalks of flax, which she had laid in order upon the roof.
