[17] said unto her, We will be blameless of this thine oath which thou hast made us swear. [18] Behold, when we come into the land, thou shalt bind this line of scarlet thread in the window which thou didst let us down by: and thou shalt bring thy father, and thy mother, and thy brethren, and all thy father's household, unto thee. [19] And it shall be, that whosoever shall go out of the doors of thy house into the street, his blood shall be upon his head, and we will be guiltless: and whosoever shall be with thee in the house, his blood shall be on our head, if any hand be upon him. [20] And if thou utter this our business, then we will be quit of thine oath which thou hast made us to swear.
