Joshua had been a spy himself, and it was natural enough that he should think of the same mode of reconnoitring the country, now that they were again on the eve of making the entrance into it which they should have made nearly forty years before. There is no reason to think that in taking this step Joshua acted presumptuously, proceeding on his own counsel when he should have sought counsel of God. For Joshua might rightly infer that he ought to take this course inasmuch as it had been followed before with God's approval in the case of the twelve. Its purpose was twofold--to obtain information and confirmation. Information as to the actual condition and spirit of the Canaanites, as to the view they took of the approaching invasion of the Israelites, and the impression that had been made on them by all the remarkable things that had happened in the desert; and confirmation,--new proof for his own people that God was with them, fresh encouragement to go up bravely to the attack, and fresh assurance that not one word would ever fail them of all the things which the Lord had promised. We follow the two men as they leave Shittim, so named from the masses of bright acacia which shed their glory over the plain; then cross the river at "the fords," which, flooded though they were, were still practicable for swimmers; enter the gates of Jericho, and move along the streets. In such a city as Jericho, and among such an immoral people as the Canaanites, it was not strange that they should fall in with a woman of Rahab's occupation, and should receive an invitation to her house. Some commentators have tried to make out that she was not so bad as she is represented, but only an innkeeper; but the meaning of the word both here and as translated in Heb. xi. and James ii. is beyond contradiction. Others have supposed that she was one of the harlot-priestesses of Ashtoreth, but in that case she would have had her dwelling in the precincts of a temple, not in an out-of-the-way place on the walls of the city. We are to remember that in the degraded condition of public opinion in Canaan, as indeed much later in the case of the Hetairai of Athens, her occupation was not regarded as disgraceful, neither did it banish her from her family, nor break up the bonds of interest and affection between them, as it must do in every moral community.[6] It was not accompanied with that self-contempt and self-loathing which in other circumstances are its fruits. We may quite easily understand how the spies might enter her house simply for the purpose of getting the information they desired, as modern detectives when tracking out crime so often find it necessary to win the confidence and worm out the secrets of members of the same wretched class. But the emissaries of Joshua were in too serious peril, in too devout a mood, and in too high-strung a state of nerve to be at the mercy of any Delilah that might wish to lure them to careless pleasure.
