Jesus asked Peter three times if he really loved Jesus. Then Jesus told Peter how Peter would die.

John 21:15-19

15 When we had finished eating, Jesus said to Simon Peter, “John’s son Simon, do you love me more than these other disciples do?” Peter said to him, “Yes, Lord, you know that you are dear to me (OR, that I love you).” Jesus said, “Give to those who belong to me what they need spiritually, like [MET] a shepherd provides food for his lambs.” 16 Jesus said to him again, “John’s son Simon, do you love me?” He replied, “Yes, Lord, you know that you are dear to me (OR, that I love you).” Jesus said to him, “Take care of those who belong to me, like [MET] a shepherd takes care of his sheep.” 17 Jesus said to him a third time, “John’s son Simon, am I really dear to you (OR, do you really love me)?” Peter was grieved because Jesus asked him this three times, and because the third time he changed the question. He said, “Lord, you know everything. You know that you are dear to me (OR, that I love you).” Jesus said, “Give to those who belong to me what they need spiritually, as [MET] a shepherd provides food for his sheep. 18 Now listen to this carefully: When you were young, you put your clothes on by yourself, and you went wherever you wanted to go. But when you are old, you will stretch out your arms, and someone will fasten them with a rope and will lead you to a place where you do not want to go.” 19 Jesus said this to indicate how Peter would die ◄violently/on a cross► in order to honor God. Then Jesus said to him, “Keep being my faithful disciple until you die.”
