2. And it was told the king, etc. It is probable that watchmen had been appointed to take notice of suspicious strangers, as is wont to be done in doubtful emergencies, or during an apprehension of war. The Israelites were nigh at hand; they had openly declared to the Edomites and Moabites that they were seeking a settlement in the land of Canaan; they were formidable for their number; they had already made a large conquest after slaying two neighboring kings; and as we shall shortly perceive, their famous passage of the Red Sea had been noised abroad. It would therefore have argued extreme supineness in such manifest danger to allow any strangers whatever to pass freely through the city of Jericho, situated as it was on the frontiers.
It is not wonderful, therefore, that men who were unknown and who appeared from many circumstances to have come with a hostile intention, were denounced to the king. At the same time, however, we may infer that they were supernaturally blinded in not guarding their gates more carefully; for with the use of moderate diligence the messengers after they had once entered might easily have been detained. Nay, a search ought forthwith to have been instituted, and thus they would to a certainty have been caught. The citizens of Jericho were in such trepidation and so struck with judicial amazement, that they acted in everything without method or counsel. Meanwhile the two messengers were reduced to such extremities that they seemed on the eve of being delivered up to punishment. The king sends for them; they are lurking in the house; their life hangs upon the tongue of a woman, just as if it were hanging by a thread. Some have thought that there was in this a punishment of the distrust of Joshua, who ought to have boldly passed the Jordan, trusting to the divine guidance. But the result would rather lead us to conclude differently, that God by rescuing the messengers from extreme danger gave new courage to the people; for in that manifestation of his power he plainly showed that he was watching over their safety, and providing for their happy entrance into the promised land.
