Joshua 2:17-20

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

18Behold, when we come into the land, thou shalt bind in the window this line of scarlet thread by which thou hast let us down; and thou shalt gather to thee in the house thy father, and thy mother, and thy brethren, and all thy father's household;

19and it shall be, that whoever shall go out of the doors of thy house into the street, — his blood shall be upon his head, and we shall be innocent; but every one who shall be with thee in the house, his blood shall be upon our head, if any hand be upon him.

20And if thou make known this our business, we will be quit of thine oath which thou hast made us swear.
