John 21:1-3 After these things Emmanuel showed himself again to the disciples at the sea of Tiberias and on this wise showed he himself. There were together Simon Peter and Thomas called Didymus and Nathanael of Cana in Galilee and the sons of Zebedee and two other of his disciples. Simon Peter said unto them, I go a fishing. They say unto him, We also go with you. They went forth and entered into a ship immediately and that night they caught nothing.

John 21:4-6 But when the morning was now come, Emmanuel stood on the shore, but the disciples knew not that it was Emmanuel. Then Emmanuel said unto them, Children, have you any meat? They answered him, No. And he said unto them, Cast the net on the right side of the ship and you shall find. They cast therefore and now they were not able to draw it for the multitude of fishes. 

John 21:7 Therefore that disciple whom Emmanuel loved.(John).said unto Peter, It is the Lord. Now when Simon Peter heard that it was the Lord, he girt.(wrapped around and fastened).his fisher's coat unto him, for he was naked and did cast himself into the sea.

Adam Clarke's Commentary:."It is likely that they were in very shallow water and as they were only two hundred cubits from the land, about one hundred and thirty-two English yards, it is possible that Peter only stepped into the water that he might assist them to draw the boat to land, which was now heavily laden. It is not likely that he went into the water in order to swim ashore. Had he intended this, it is not to be supposed that he would have put his great coat on, which would then have been an essential hinderance to him in getting to shore."

John 21:8-11 And the other disciples came in a little ship, for they were not far from land, but as it were two hundred cubits, dragging the net with fishes. As soon then as they were come to land, they saw a fire of coals there and fish laid thereon and bread. Emmanuel said unto them, Bring of the fish which you have now caught. Simon Peter went up and drew the net to land full of great fishes, an hundred and fifty and three. And for all there were so many, yet was not the net broken.

John 21:12 Emmanuel said unto them, Come and dine. And none of the disciples durst.(dare, to be bold).ask him, Who are you? Knowing that it was the Lord.

John 21:13 Christ then came and took bread and gave it to them and fish likewise.

John 21:14 This is now the third time that Christ showed himself to his disciples, after that he was risen from the dead.(*).

John 21:15 So when they had dined, Emmanuel the Christ said to Simon Peter, Simon, son of Jonas, do you love you me more than these?.(referring to the success Peter had fishing, see verses 1-14; after Emmanuel's resurrection, the disciples went back to their old lifestyle of fishing, etc., but they had another purpose which Christ here makes them well aware of).He said unto him, Yea, Lord, you know that I love you. He said unto him, Feed my lambs.

John 21:16 He said to him again the second time, Simon, son of Jonas, love you me? He said unto him, Yea, Lord, you know that I love you. He said unto him, Feed my sheep.

John 21:17 He said unto him the third time, Simon, son of Jonas, love you me? Peter was grieved because he said unto him the third time, Love you me? And he said unto him, Lord, you know all things; you know that I love you. Emmanuel said unto him, Feed my sheep.

John 21:18 Verily, verily, I say unto you, When you were young, you girded yourself and walked where you wanted, but when you shall be old, you shall stretch forth your hands and another shall gird you and carry you where you would not. 

Adam Clarke's Commentary:.'You shalt stretch forth your hands' Wetstein observes that it was a custom at Rome to put the necks of those who were to be crucified into a yoke and to stretch out their hands and fasten them to the end of it and having thus led them through the city they were carried out to be crucified. Thus then Peter was girded (bound), chained and carried (forced) whither he would not want to go, not that he was unwilling to die for Christ, but he was a man, he did not love death, but he loved his life less than he loved God.
Barnes Notes: 'carry you', compel you.

John 21:19 This spake he, signifying by what death he should glorify God. And when he had spoken this, he said unto him, Follow me.

1Corinthians 11:1.

John 21:20 Then Peter turning around, sees the disciple whom Emmanuel loved, following, the disciple which also leaned on his breast at supper and said, Lord, which is he that is going to betray you? 

John 21:21-23 Peter seeing him said to Emmanuel, Lord and what shall this man do? Emmanuel said unto him, If I will that he tarry till I come, what is that to you? follow you me. Then went this saying abroad among the brethren, that that disciple should not die; yet Emmanuel said not unto him, He shall not die; but, If I will that he tarry till I come, what is that to you?

We all have a hard time getting correct exactly what others say. It's important to listen and get the intent of what another may be saying.

John 21:24 This is the disciple which testified of these things and wrote these things and we know that his testimony is true.

John 21:25 And there are also many other things which Emmanuel did.(why.He came to Earth), the which, if they should be written every one, I suppose that even the world itself could not contain the books that should be written. Amen.
