8 Before the spies went to sleep that night, Rahab went up on the roof to talk with them. 9 "I know the Lord has given you this land," she told them. "We are all afraid of you. Everyone in the land is living in terror. 10 For we have heard how the Lord made a dry path for you through the Red Sea when you left Egypt. And we know what you did to Sihon and Og, the two Amorite kings east of the Jordan River, whose people you completely destroyed. 11 No wonder our hearts have melted in fear! No one has the courage to fight after hearing such things. For the Lord your God is the supreme God of the heavens above and the earth below. 12 "Now swear to me by the Lord that you will be kind to me and my family since I have helped you. Give me some guarantee that 13 when Jericho is conquered, you will let me live, along with my father and mother, my brothers and sisters, and all their families." 14 "We offer our own lives as a guarantee for your safety," the men agreed. "If you don't betray us, we will keep our promise and be kind to you when the Lord gives us the land." 15 Then, since Rahab's house was built into the town wall, she let them down by a rope through the window. 16 "Escape to the hill country," she told them. "Hide there for three days from the men searching for you. Then, when they have returned, you can go on your way." 17 Before they left, the men told her, "We will be bound by the oath we have taken only if you follow these instructions. 18 When we come into the land, you must leave this scarlet rope hanging from the window through which you let us down. And all your family members-your father, mother, brothers, and all your relatives-must be here inside the house. 19 If they go out into the street and are killed, it will not be our fault. But if anyone lays a hand on people inside this house, we will accept the responsibility for their death. 20 If you betray us, however, we are not bound by this oath in any way." 21 "I accept your terms," she replied. And she sent them on their way, leaving the scarlet rope hanging from the window.

Rahab had heard of the miracles the Lord wrought for Israel. She believed that his promises would certainly be fulfilled, and his threatenings take effect; and that there was no way of escape but by submitting to him, and joining with his people. The conduct of Rahab proved that she had the real principle of Divine faith. Observe the promises the spies made to her. The goodness of God is often expressed by his kindness and truth, Psalm 117:2; in both these we must be followers of him. Those who will be conscientious in keeping promises, are cautious in making them. The spies make needful conditions. The scarlet cord, like the blood upon the doorpost at the passover, recalls to remembrance the sinner's security under the atoning blood of Christ; and that we are to flee thereto for refuge from the wrath of a justly offended God. The same cord Rahab used for the saving of these Israelites, was to be used for her own safety. What we serve and honour God with, we may expect he will bless, and make useful to us.
