Acts 9.1-6

And Saul, yet breathing out threatenings and slaughter against the disciples of the Lord, went unto the high priest,
And desired of him letters to Damascus to the synagogues, that if he found any of this way, whether they were men or women, he might bring them bound unto Jerusalem.
And as he journeyed, he came near Damascus: and suddenly there shined round about him a light from heaven:
And he fell to the earth, and heard a voice saying unto him, Saul, Saul, why persecutest thou me?
And he said, Who art thou, Lord? And the Lord said, I am Jesus whom thou persecutest: it is hard for thee to kick against the pricks.
And he trembling and astonished said, Lord, what wilt thou have me to do? And the Lord said unto him, Arise, and go into the city, and it shall be told thee what thou must do.

John 21.1-19

After these things Jesus shewed himself again to the disciples at the sea of Tiberias; and on this wise shewed 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 saith unto them, I go a fishing. They say unto him, We also go with thee. They went forth, and entered into a ship immediately; and that night they caught nothing.
But when the morning was now come, Jesus stood on the shore: but the disciples knew not that it was Jesus.
Then Jesus saith unto them, Children, have ye any meat? They answered him, No.
And he said unto them, Cast the net on the right side of the ship, and ye shall find. They cast therefore, and now they were not able to draw it for the multitude of fishes.
Therefore that disciple whom Jesus loved saith unto Peter, It is the Lord. Now when Simon Peter heard that it was the Lord, he girt his fisher’s coat unto him, (for he was naked,) and did cast himself into the sea.
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.
Jesus saith unto them, Bring of the fish which ye 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.
Jesus saith unto them, Come and dine. And none of the disciples durst ask him, Who art thou? knowing that it was the Lord.
Jesus then cometh, and taketh bread, and giveth them, and fish likewise.
This is now the third time that Jesus shewed himself to his disciples, after that he was risen from the dead.
So when they had dined, Jesus saith to Simon Peter, Simon, son of Jonas, lovest thou me more than these? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my lambs.
He saith to him again the second time, Simon, son of Jonas, lovest thou me? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my sheep.
He saith unto him the third time, Simon, son of Jonas, lovest thou me? Peter was grieved because he said unto him the third time, Lovest thou me? And he said unto him, Lord, thou knowest all things; thou knowest that I love thee. Jesus saith unto him, Feed my sheep.
Verily, verily, I say unto thee, When thou wast young, thou girdest thyself, and walkedst whither thou wouldest: but when thou shalt be old, thou shalt stretch forth thy hands, and another shall gird thee, and carry thee whither thou wouldest not.
This spake he, signifying by what death he should glorify God. And when he had spoken this, he saith unto him, Follow me.
