8 And before they had lain down, she went up to them upon the roof; 9 and said to the men, I know that Jehovah has given you the land, and that the dread of you has fallen on us, and that all the inhabitants of the land faint because of you. 10 For we have heard that Jehovah dried up the waters of the Red sea before you when ye came out of Egypt; and what ye did to the two kings of the Amorites that were beyond the Jordan, to Sihon and to Og, whom ye utterly destroyed. 11 We heard [of it], and our heart melted, and there remained no more spirit in any man because of you; for Jehovah your God, he is God in the heavens above and on the earth beneath. 12 And now, I pray you, swear to me by Jehovah, since I have dealt kindly with you, that ye will also deal kindly with my father's house, and give me a certain sign, 13 that ye will let my father live, and my mother, and my brethren, and my sisters, and all that belong to them, and deliver our souls from death. 14 And the men said to her, Our lives shall pay for yours, if ye do not make this our business known; and it shall be when Jehovah shall give us the land, that we will deal kindly and truly with thee. 15 And she let them down by a cord through the window; for her house was upon the city-wall, and she dwelt upon the wall. 16 And she said to them, Go to the mountain, that the pursuers may not meet with you; and hide yourselves there three days, until the pursuers have returned; and afterwards go your way. 17 And the men said to her, We will be quit of this thine oath which thou hast made us swear. 18 Behold, when we come into the land, thou shalt bind in the window this line of scarlet thread by which thou hast let us down; and thou shalt gather to thee in the house thy father, and thy mother, and thy brethren, and all thy father's household; 19 and it shall be, that whoever shall go out of the doors of thy house into the street,—his blood shall be upon his head, and we shall be innocent; but every one who shall be with thee in the house, his blood shall be upon our head, if any hand be upon him. 20 And if thou make known this our business, we will be quit of thine oath which thou hast made us swear. 21 And she said, According to your words, so be it. And she sent them away, and they departed. And she bound the scarlet line in the window.

Commentary on Joshua 2:8-21
(Read Joshua 2:8-21)
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.
