Joshua 2:17-20

17The men said to her, ‘If you do what we say, we will do what we have promised.

18We will soon attack this land. So tie this red string in the window that we came through. Bring your father, your mother, your brothers and sisters and all your family into your house.

19If any of them leaves your house, they may die. If that happens, we will not be guilty. We will only be guilty if our soldiers hurt anyone who is in your house.

20But if you tell anyone about us, we do not have to do what we have promised to you.’
