And the king of Jericho sent to Rahab, saying: Bring forth the men that came to thee, and are entered into thy house: for they are spies, and are come to view all the land.

“"By faith Rahab the prostitute did not perish with those who were disobedient, having received the spies, but she directed their departure by another road." And pay attention to how much wisdom she blended with her prudence. When those sent by the king came and requested the spies, they ask her, "Did men enter in here and come near you?" She answers them, "Yes, they entered in." First she builds the truth, and then she applies the lie on top. For no lie like this becomes believable unless it first reveals the truth. For this reason all who tell lies probably to be believed, first speak of truths and reveal confessions and later add the lies and things which are questionable. "Spies entered in here and came near you?" "Yes," she says. If she had said "no" from the beginning, she would have challenged the messengers to investigate. However, "they entered in," she says, "and they came out and escaped by such and such a road. Pursue them and you will capture them." O this good lie! O this good fraud, which does not betray the divine but safeguards the sacred! When the mouths of saints preach the repentance that made Rahab worthy of such salvation, for example, Joshua the son of Nun, who shouts in the desert, "Let Rahab the prostitute live"; and Paul, who says, "By faith Rahab the prostitute did not perish with those who were disobedient," will we not receive salvation even more so when we offer to God our repentance?”

“And the king of Jericho sent unto Rahab,.... Not merely because she kept a public house, or being a prostitute had often strangers in it, and so conjectured that the men he had notice of might be there; but he sent upon certain information that they were seen to go in there, as it follows: saying, bring forth the men that are come to thee; not to commit lewdness with her, though this is the sense some Jewish commentators give; but this neither agrees with the character of the men Joshua had chosen for this purpose, nor answers any end of the king to suggest; nor can it be thought that Rahab would so openly and freely own this, as in Jos 2:4, but what is meant by the phrase is explained in the following clause: which are entered into thine house: in order to lodge there that night: for they be come to search out all the country; so it was suspected, nor was the suspicion groundless.”

“The king of Jericho sent unto Rahab - This appears to be a proof of the preceding opinion: had she been a prostitute or a person of ill fame he could at once have sent officers to have seized the persons lodged with her as vagabonds; but if she kept a house of entertainment, the persons under her roof were sacred, according to the universal custom of the Asiatics, and could not be molested on any trifling grounds. A guest or a friend is sacred in whatever house he may be received, in every part of the east to the present day.”

“House. She spoke to them through a window. The messengers did not enter into her house; whence Serarius infers, that Rahab was a person consecrated to some impure deity, and therefore held in some estimation among the people of Jericho, as this was a city of the moon, in whose honour such consecrations were generally made. But these arguments are not very convincing. (Calmet)”
