Joshua 2:17-21

The men said to her, “We will be guiltless with respect to this oath of yours that you have made us swear. Behold, when we come into the land, you shall tie this scarlet cord in the window through which you let us down, and you shall gather into your house your father and mother, your brothers, and all your father’s household. Then if anyone goes out of the doors of your house into the street, his blood shall be on his own head, and we shall be guiltless. But if a hand is laid on anyone who is with you in the house, his blood shall be on our head. But if you tell this business of ours, then we shall be guiltless with respect to your oath that you have made us swear.” And she said, “According to your words, so be it.” Then she sent them away, and they departed. And she tied the scarlet cord in the window.
