Joshua 2:17-20

17Then the men said to her: “We will be released from this oath that you have made us swear,

18unless when we come into the land, you tie this line of scarlet thread in the window through which you lowered us down, and gather to yourself in the house your father, your mother, your brothers and all your father’s household—

19whoever goes out of the doors of your house into the street, his blood will be on his head and we will be innocent, but whoever is with you in the house, his blood will be on our head if any hand is laid on him.

20But if you divulge this business of ours, then we will be released from your oath you have made us swear.”
