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.
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.
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.
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.
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.
Matthew Henry's Commentary on Joshua 2:18
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.
