John 13:36

Simon Peter said unto him, Lord, whither goest thou? — Comp. John 13:33. The earnest, loving nature of the Apostle dwells upon the words which tell of the Master’s departure. He is prepared to follow Him to danger, or even to death, and, that he may do so, asks whither it is that He is going.

Whither I go, thou canst not follow me now. — Our Lord does not give the answer which St. Peter had sought, but repeats the statement of John 13:33. For St. Peter, as for the others, the place must be prepared and the way opened before they could follow (John 14:2). For him, as for his Master, the day’s work was to be done before the night would come, and it was not done yet. But that night would come, and he would hereafter follow his Master in a more literal sense than any of which he thought. (See Notes on John 21:18.)
