Joshua 2:21

17The men said to her, “We will be guiltless of this your oath which you’ve made us to swear.

18Behold, when we come into the land, tie this line of scarlet thread in the window which you used to let us down. Gather to yourself into the house your father, your mother, your brothers, and all your father’s household.

19It shall be that whoever goes out of the doors of your house into the street, his blood will be on his head, and we will be guiltless. Whoever is with you in the house, his blood shall be on our head, if any hand is on him.

20But if you talk about this business of ours, then we shall be guiltless of your oath which you’ve made us to swear.”

21She said, “Let it be as you have said.” She sent them away, and they departed. Then she tied the scarlet line in the window.

22They went and came to the mountain, and stayed there three days, until the pursuers had returned. The pursuers sought them all along the way, but didn’t find them.

23Then the two men returned, descended from the mountain, crossed the river, and came to Joshua the son of Nun. They told him all that had happened to them.

24They said to Joshua, “Truly the LORD has delivered all the land into our hands. Moreover, all the inhabitants of the land melt away before us.”
