Then took they him, and led him, and brought him into the high priest’s house. And Peter followed affar off. And when they had kindled a fire in the midst of the hall, and were set down together, Peter sat down among them. But a certain maid beheld him as he sat by the fire, and earnestly looked upon him, and said, This man was also with him. And he denied him, saying, Woman, I know him not. And after a little while another saw him, and said, Thou art also of them. And Peter said, Man, I am not. And about, the space of one hour after another confidently affirmed, saying, Of a truth this fellow also was with him: for he is a Galilæan. And Peter said, Man, I know not what thou sayest. And immediately, while he yet spake, the cock crew. And the Lord turned, and looked upon Peter. And Peter remembered the word of the Lord, how he had said unto him, Before the cock crow, thou shalt deny me thrice. And Peter went out, and wept bitterly.
(de Con. Ev. ut sup.) What Matthew and Mark call after a little while, Luke explains by saying, about the space of one hour after; but with regard to the space of time, John says nothing. Likewise when Matthew and Mark record not in the singular but in the plural number those who conversed with Peter, while Luke and John speak of one, we may easily suppose either that Matthew and Mark used the pluralfor the singular by a common form of speech, or that one person in particular addressed Peter, as being the one who had seen him, and that others trusting to his credit joined in pressing him. But now as to the words which Matthew asserts were said to Peter himself, Truly thou art one of them, for thy speech bewrayeth thee; as also those which to the same Peter John declared to have been said, Did not I see thee in the garden? whereas Mark and Luke state that they spoke to one another concerning Peter; we either believe that they held the right opinion who say that they were really addressed to Peter; (for what was said concerning him in his presence amounts to the same as if it had been said to him;) or that they were said in both ways, and that some of the Evangelists related them one way, some the other.
