Joshua 2:17-20

17Before they left, the men told her, “We will be bound by the oath we have taken only if you follow these instructions.

18When we come into the land, you must leave this scarlet rope hanging from the window through which you let us down. And all your family members—your father, mother, brothers, and all your relatives—must be here inside the house.

19If they go out into the street and are killed, it will not be our fault. But if anyone lays a hand on people inside this house, we will accept the responsibility for their death.

20If you betray us, however, we are not bound by this oath in any way.”
