Joshua 2:15-18

15Then she let them down by a cord through the window: for her house was upon the town wall, and she dwelt upon the wall.

16And she said unto them, Get you to the mountain, lest the pursuers meet you; and hide yourselves there three days, until the pursuers be returned: and afterward may ye go your way.

17And the men said unto her, We will be blameless of this thine oath which thou hast made us swear.

18Behold, when we come into the land, thou shalt bind this line of scarlet thread in the window which thou didst let us down by: and thou shalt bring thy father, and thy mother, and thy brethren, and all thy father’s household, home unto thee.1
