17 And the men said unto her, We will be blameless of this thine oath which thou hast made us 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 bring [1] thy father, and thy mother, and thy brethren, and all thy father's household, home unto thee.
17 Now the men had said to her, "This oath you made us swear will not be binding on us 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, your brothers and all your family into your house.
17 The men said to her, "We will be guiltless with respect to this oath of yours that you have made us swear. 18 Behold, when we come into the land, you shall tie this scarlet cord in the window through which you let us down, and you shall gather into your house your father and mother, your brothers, and all your father's household.
17 The men told her, "In order to keep this oath you made us swear, 18 here is what you must do: Hang this red rope out the window through which you let us down and gather your entire family with you in your house - father, mother, brothers, and sisters.
17 So the men said to her: "We will be blameless of this oath of yours which you have made us swear, 18 unless, when we come into the land, you bind this line of scarlet cord in the window through which you let us down, and unless you bring your father, your mother, your brothers, and all your father's household to your own home.
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.

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.
