When it was dark - So it appears that it was after night that the king of Jericho sent to Rahab, ordering her to produce the persons who lodged with her. The season itself was friendly to the whole plot: had these transactions taken place in daylight, it is scarcely possible that the spies could have escaped. But this is no excuse for the woman's prevarication, for God could have saved his messengers independently of her falsity. God never says to any, Do evil that good may come of it. See at the end of the chapter, Joshua 2:24 (note).

And it came to pass, about the time of the shutting of the gate,.... Of the city, which was done every night, and at a certain time:

when it was dark; the sun set, and night come on:

that the men went out; out of her house, and out of the city too, as she said, though it was a downright lie, as well as what follows:

whither the men went I wot not; though she knew they were not gone, but were now in her house; she might not scruple telling a lie, being brought up a Heathen, and being done with a design to save the lives of persons that belonged to a people she was persuaded were the people of God, and to whom he had given the land; though her lies are not to be justified; evil is not to be done that good may come; nor are men to tell lies one to another upon any account; but these sins, with others, the Lord forgave her:

pursue after them quickly, and ye shall overtake them; this she encouraged them to do, to get rid of them the sooner, and to remove all suspicion of her having any respect for them, and of being concerned in concealing them.

And it came to pass about the time of shutting of the gate, when it was dark, that the men went out: whither the men went I wot not: pursue after them quickly; for ye shall overtake them.

5. the time of shutting of the gates-The gates of all Oriental cities are closed at sunset, after which there is no possibility either of admission or egress.

the men went out-This was a palpable deception. But, as lying is a common vice among heathen people, Rahab was probably unconscious of its moral guilt, especially as she resorted to it as a means for screening her guests; and she might deem herself bound to do it by the laws of Eastern hospitality, which make it a point of honor to preserve the greatest enemy, if he has once eaten one's salt. Judged by the divine law, her answer was a sinful expedient; but her infirmity being united with faith, she was graciously pardoned and her service accepted (Jas 2:25).

2:1-7 Faith in God's promises ought not to do away, but to encourage our diligence in the use of proper means. The providence of God directed the spies to the house of Rahab. God knew where there was one that would be true to them, though they did not. Rahab appears to have been an innkeeper; and if she had formerly been one of bad life, which is doubtful, she had left her evil courses. That which seems to us most accidental, is often overruled by the Divine providence to serve great ends. It was by faith that Rahab received those with peace, against whom her king and country had war. We are sure this was a good work; it is so spoken of by the apostle, Jas 2:25; and she did it by faith, such a faith as set her above the fear of man. Those only are true believers, who find in their hearts to venture for God; they take his people for their people, and cast in their lot among them. The spies were led by the special providence of God, and Rahab entertained them out of regard to Israel and Israel's God, and not for lucre or for any evil purpose. Though excuses may be offered for the guilt of Rahab's falsehood, it seems best to admit nothing which tends to explain it away. Her views of the Divine law must have been very dim: a falsehood like this, told by those who enjoy the light of revelation, whatever the motive, would deserve heavy censure.
