Lucas 7:39

Now when the Pharisee that had bidden him saw it, he spake within himself, saying, This man, if he were a prophet, would have perceived who and what manner of woman this is that toucheth him, that she is a sinner.

Spake within himself ... Only in the word of God may it be read what men said within themselves, and Luke has several such instances: the prodigal son (Luke 15:17), the unjust steward (Luke 16:3), etc. This Pharisee was correct in one of the premises of his conceited syllogism, namely, that a true prophet would have known who and what manner of person the woman was. However, he was wrong in his companion premise that Jesus did not know who and what manner of person the woman was. He not only knew that but also knew all about Simon, as the conversation at once revealed.
