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.
