In His third question Jesus used a word for “love” different from that which He used in the first two. Whether a difference of meaning is intended is open to question. See on v. 15 for the significance of the question if the new word for “love” is to be distinguished from the preceding.

 See on v. 15 for a possible cause of grief. Peter knew he had given cause for others to doubt his love for his Master. The repeated questions brought his shameful denials vividly to mind, and like a barbed arrow must have cut his wounded heart.

 The third time Peter omitted the “yea,” or “yes” (see vs. 15, 16).

He appealed to the all-seeing eye that read the innermost secrets of his life.

 Jesus here repeats the charge (cf. vs. 15, 16). Peter had shown himself to be fully repentant. His heart was tender and full of love. He could now be entrusted with the flock.
