John Calvin's Bible Commentary
Joshua 2:7
7.And the men pursued, etc. Their great credulity shows that God had blinded them. Although Rahab had gained much by deluding them, a new course of anxiety intervenes; for the gates being shut, the city like a prison excluded the hope of escape. They were therefore again aroused by a serious trial to call upon God. For seeing that this history was written on their report, it is impossible they could have been ignorant of what was then going on, especially as God, for the purpose of magnifying his grace, purposely exposed them to a succession of dangers. And now when they were informed that search was made for them, we infer from the fact of their being still awake, that they were in anxiety and alarm. Their trepidation must have been in no small degree increased when it was told them that their exit was precluded.
It appears, however, that Rahab was not at all dismayed, since she bargains with so much presence of mind, and so calmly, for her own safety and that of her family. And in this composure and firmness her faith, which is elsewhere commended, appears conspicuous. For on human principles she never would have braved the fury of the king and people, and become a suppliant to guests half dead with terror. Many, indeed, think there is something ridiculous in the eulogium bestowed upon her both by St. James and the author of the Epistle to the Hebrews, (James 2:25; Hebrews 11:31,) when they place her in the catalogue of the faithful. But any one who will carefully weigh all the circumstances will easily perceive that she was endowed with a lively faith.
First, If the tree is known by its fruits, we here see no ordinary effects, which are just so many evidences of faith. Secondly, A principle of piety must have given origin to her conviction that the neighboring nations were already in a manner vanquished and laid prostrate, since terror sent from above had filled all minds with dismay. It is true that in profane writers also we meet with similar expressions, which God has extorted from them that he might assert his power to rule and turn the hearts of men in whatever way he pleases. But while these writers prate like parrots, Rahab declaring in sincerity of heart that God has destined the land for the children of Israel, because all the inhabitants have fainted away before them, claims for him a supreme rule over the hearts of men, a rule which the pride of the world denies.
For although the experience of all times has shown that more armies have fallen or been routed by sudden and un-looked for terror than by the force and prowess of the enemy, the impression of this truth has forthwith vanished away, and hence conquerors have always extolled their own valor, and on any prosperous result gloried in their own exertions and talents for war. They have felt, I admit, that daring and courage are occasionally bestowed or withheld by some extraneous cause, and accordingly men confess that in war fortune does much or even reigns supreme. Hence their common proverb with regard to panic terrors, and their vows made as well to Pavor (Dread) as to Jupiter Stator. (39) But it never became a serious and deep-seated impression in their minds, that every man is brave according as God has inspired him with present courage, or cowardly according as he has suppressed his daring. Rahab, however, recognizes the operation of a divine hand in striking the nations of Canaan with dismay, and thus making them as it were by anticipation pronounce their own doom; and she infers that the terror which the children of Israel have inspired is a presage of victory, because they fight under God as their Leader.
In the fact, that while the courage of all had thus melted away, they however prepared to resist with the obstinacy of despair; we see that when the wicked are broken and crushed by the hand of God, they are not so subdued as to receive the yoke, but in their terror and anxiety become incapable of being tamed. Here, too, we have to observe how in a common fear believers differ from unbelievers, and how the faith of Rahab displays itself. She herself was afraid like any other of the people; but when she reflects that she has to do with God, she concludes that her only remedy is to eschew evil by yielding humbly and placidly, as resistance would be altogether unavailing. But what is the course taken by all the wretched inhabitants of the country? Although terror-struck, so far is their perverseness from being overcome that they stimulate each other to the conflict.
