8 And before they were laid down, she came up unto them upon the roof; 9 and she said unto the men, I know that Jehovah hath given you the land, and that the fear of you is fallen upon us, and that all the inhabitants of the land melt away before you. 10 For we have heard how Jehovah dried up the water of the Red Sea before you, when ye came out of Egypt; and what ye did unto the two kings of the Amorites, that were beyond the Jordan, unto Sihon and to Og, whom ye utterly destroyed. 11 And as soon as we had heard it, our hearts did melt, neither did there remain any more spirit in any man, because of you: for Jehovah your God, he is God in heaven above, and on earth beneath. 12 Now therefore, I pray you, swear unto me by Jehovah, since I have dealt kindly with you, that ye also will deal kindly with my father's house, and give me a true token; 13 and that ye will save alive my father, and my mother, and my brethren, and my sisters, and all that they have, and will deliver our lives from death. 14 And the men said unto her, Our life for yours, if ye utter not this our business; and it shall be, when Jehovah giveth us the land, that we will deal kindly and truly with thee. 15 Then she let them down by a cord through the window: for her house was upon the side of the wall, and she dwelt upon the wall. 16 And she said unto them, Get you to the mountain, lest the pursuers light upon you; and hide yourselves there three days, until the pursuers be returned: and afterward may ye go your way. 17 And the men said unto her, We will be guiltless of this thine oath which thou hast made us to swear. 18 Behold, when we come into the land, thou shalt bind this line of scarlet thread in the window which thou didst let us down by: and thou shalt gather unto thee into the house thy father, and thy mother, and thy brethren, and all thy father's household. 19 And it shall be, that whosoever shall go out of the doors of thy house into the street, his blood shall be upon his head, and we shall be guiltless: and whosoever shall be with thee in the house, his blood shall be on our head, if any hand be upon him. 20 But if thou utter this our business, then we shall be guiltless of thine oath which thou hast made us to swear. 21 And she said, According unto 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.
