(67) Thou also wast with Jesus of Nazareth.—The order of the words varies in the MSS.; but the better ones give the words as spoken with an emphatic scorn, “And thou also wast with the Nazarene, Jesus.”

14:66-72 Peter's denying Christ began by keeping at a distance from him. Those that are shy of godliness, are far in the way to deny Christ. Those who think it dangerous to be in company with Christ's disciples, because thence they may be drawn in to suffer for him, will find it much more dangerous to be in company with his enemies, because there they may be drawn in to sin against him. When Christ was admired and flocked after, Peter readily owned him; but will own no relation to him now he is deserted and despised. Yet observe, Peter's repentance was very speedy. Let him that thinketh he standeth take heed lest he fall; and let him that has fallen think of these things, and of his own offences, and return to the Lord with weeping and supplication, seeking forgiveness, and to be raised up by the Holy Spirit.See this fully explained in the notes at Matthew 26:57-75. 67. And when she saw Peter warming himself, she looked upon him—Luke (Lu 22:56) is here more graphic; "But a certain maid beheld him as he sat by the fire"—literally, "by the light," which, shining full upon him, revealed him to the girl—"and earnestly looked upon him"—or, "fixed her gaze upon him." His demeanor and timidity, which must have attracted notice, as so generally happens, "leading," says Olshausen, "to the recognition of him."

and said, And thou also wast with Jesus of Nazareth—"with Jesus the Nazarene," or, "with Jesus of Galilee" (Mt 26:69). The sense of this is given in John's report of it (Joh 18:17), "Art not thou also one of this man's disciples?" that is, thou as well as "that other disciple," whom she knew to be one, but did not challenge, perceiving that he was a privileged person. In Luke (Lu 22:56) it is given as a remark made by the maid to one of the by-standers—"this man was also with Him." If so expressed in Peter's hearing—drawing upon him the eyes of every one that heard it (as we know it did, Mt 26:70), and compelling him to answer to it—that would explain the different forms of the report naturally enough. But in such a case this is of no real importance.

And when she saw Peter warming himself,.... At the life which was in the midst of the hall:

she looked upon him; very earnestly, knowing him to be the same, she had let in at the motion of one, that was known in the high priest's family; and suspecting him, by being a stranger, and by his looks:

and said, and thou also wast with Jesus of Nazareth; that is, one of his disciples; See Gill on Matthew 26:69.

And when she saw Peter warming himself, she looked upon him, and said, And thou also wast with Jesus of Nazareth.
