John 18:17
Then saith the damsel that kept the door unto Peter, Art not thou also one of this man's disciples? He saith, I am not.
Then saith the damsel that kept the door unto Peter,.... She being relieved, either by her father, if porter, or by a fellow servant, had the opportunity of coming into the hall, where Peter was, and was curious to observe him, who he should be, that that person of note should order him to be admitted, when an affair of so much privacy and importance was transacting; and either by Peter's language, or the trouble that appeared in his countenance, or fancying: she had seen him in the temple, or in some part of the city in company With Jesus, addresses him after this manner:
Art not thou also one of this man's disciples? She speaks of Christ in the vulgar dialect of the Jews, calling him "this man"; not only esteeming him a mere man, but a worthless man; and knowing he had disciples, challenges him as one of them; when he, all in flight and surprise, not expecting such a question to be put to him, without any further thought, rashly and suddenly
he saith I am not: he never denied that Christ was God or the Son of God, or that he was come in the flesh, or that he was the Messiah and Saviour of sinners; but either that he did not know what the maid said, or the person she spoke of; or, as here, that he was one of his disciples; which was a very great untruth: and many are the aggravations of his fall; which came to pass as soon as ever he was entered almost; and that by the means of a maid, a servant maid, a very inferior one; and at first perhaps they were alone; and the question put to him might not be in a virulent way, nor proceed from malice, but commiseration of him; and yet he had not resolution enough to own himself a disciple of Jesus; which he might have done, and in all likelihood might have gone safe off directly: but he that had so much confidence as to say, though all men deny thee, yet will not I; and had so much courage, as, in the face of a band of soldiers, to draw his sword, and smite one of the high priest's servants, but a few hours before, has not spirit enough in him to own his master before a servant maid!
