Again Jesus said, “Simon son of John, do you truly love me?” He answered, “Yes, Lord, you know that I love you.” Jesus said, “Take care of my sheep.”
Jesus repeated His previous question without adding the “more than these.” Peter’s reply was the same as before and the response of Jesus to Peter’s reply was essentially the same although a verb with a broader meaning (poimaino), which means “to exercise the office of shepherd, or tend a flock” instead of just “feed” (bosko) as in the previous verse. This is probably not significant and is just a variety in words to convey exactly the same meaning.
