Then Peter said unto him, Lord, speakest thou this parable unto us, or even to all? Peter's question here referred evidently to the longer and more important parable-story, where the reward which the faithful watchers were to receive is mentioned (Luke 12:37).
The grandeur of that reward seems deeply to have impressed the impulsive apostle. Some true conception of the heaven-life had entered into Peter's mind; we know, too, that now and again dimly Peter seemed to grasp the secret of his Master's awful Divinity.

The same curious perplexity evidently passed through Peter's mind when, on the evening before the death, in a symbol-act the Master repeated the words of the great promise made here, and washed his disciples' feet.
Then we read how Peter said to him, "Lord, dost thou wash my feet?" Were all who followed Jesus to share in that strange, mighty promise; or only a few, such as Peter and his companions, called for a special purpose?
