John 4:29 - Matthew Poole's English Annotations on the Holy Bible

She invites them to him under the notion of a man, who had told her all things that she ever did. Christ doubtless had told her, and spoken to her, much more than John hath left us upon sacred record; yet not all things she ever did, but all things (as often) signifies many things, and those such things as she might know that he who could tell those things could have told her all things, if they had been so proper for him to have repeated to her as those things which he did tell her. This induced her to believe that he was the Messiah; she offereth it to their opinion and judgment.
