Joshua 2:17

13 that you will spare the lives of my father and mother, my brothers and sisters, and all who belong to them, and that you will deliver us from death.”

14 “Our lives for your lives!” the men agreed. “If you do not report our mission, we will show you kindness and faithfulness when the LORD gives us the land.”

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.
