Joshua 2:5

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.

The time of shutting of the gate. The gates of all Oriental cities are closed at sunset, after which there is no possibility either of admission or egress; and in the East there is scarcely any twilight; 'sunset,' therefore, is a period 'when it is dark.'

The men went out. This was a palpable deception. But, as lying is a common vice among pagan 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 honour 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 (James 2:25).
