Verse 12. ? Kindness. The original is perhaps a little stronger, and involves usually the idea of mercy and pity. This, however, is not always the case (see Genesis 21:23; 2 Samuel 10:2). "It had been an ill nature in Rahab if she had been content to be saved alone: that her love might be a match to her faith, she covenants for all her family, and so returns life to those of whom she received it," (Bp. Hall). A true token. Literally, a token of truth. The construction is that in which the latter noun often stands in Hebrew for an adjective. Here, however, it would seem to be a little more, a token of truth - a pledge, that is, of sincerity. Rahab wanted some guarantee that her life and the lives of her kindred would be saved. The bare word of the spies would not suffice, for how could she and her kindred be identified in the confusion attending the sack of the city? But if the spies would agree upon some sign by which she could be recognised, it would at once be a pledge that they intended to keep their word, and a means of protection in the approaching downfall of the city.

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, Ps 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.Now therefore, I pray you, swear unto me by the Lord,.... Which being a religious action, and done by men that feared the Lord, she knew it would be binding upon them: the Targum is,"swear to me by the Word of the Lord:"

since I have showed you kindness; by receiving them with peace into her house, and hiding them when inquired for and demanded of her; in doing which she risked her own, life, had this treachery to her country, as it would have been deemed, been discovered;

that you will also show kindness unto my father's house; she mentions not herself and household, for if this was granted that would be implied and included; and this she presses for by the law of retaliation and friendship, for since she had shown kindness to them, it was but reasonable it should be returned:

and give me a true token; that she and her father's house would be saved by them when the city should be taken and the inhabitants destroyed; a token that would not deceive her, on which she might depend, and would be firm and sure.
