Joshua 2:19

15 Then Rahab let them down by a rope through the window, since the house where she lived was built into the wall of the city.

16 “Go to the hill country,” she said, “so that your pursuers will not find you. Hide yourselves there for three days until they have returned; then go on your way.”

17 The men said to her, “We will not be bound by this oath you made us swear

18 unless, when we enter the land, you have tied this scarlet cord in the window through which you let us down, and unless you have brought your father and mother and brothers and all your family into your house.

19 If anyone goes out the door of your house into the street, his blood will be on his own head, and we will be innocent. But if a hand is laid on anyone with you in the house, his blood will be on our heads.

20 And if you report our mission, we will be released from the oath you made us swear.”

21 “Let it be as you say,” she replied, and she sent them away. And when they had gone, she tied the scarlet cord in the window.

22 So the spies went out into the hill country and stayed there three days, until their pursuers had returned without finding them, having searched all along the road.

23 Then the two men started back, came down from the hill country, and crossed the river. So they came to Joshua son of Nun and reported all that had happened to them.
