Joshua 2:19-21

19If any of them go outside your house into the street, their blood will be on their own heads; we will not be responsible. As for those who are in the house with you, their blood will be on our head if a hand is laid on them. 20But if you tell what we are doing, we will be released from the oath you made us swear.” 21“Agreed,” she replied. “Let it be as you say.” So she sent them away, and they departed. And she tied the scarlet cord in the window.
