John 21:16

‘He says to him again a second time, “Simon, son of Joanes, do you love me?” He says to him, “Indeed, Lord, you know that I love you.” He says to him, “Shepherd my sheep”.’

The same question is repeated by Jesus and the same answer brings confirmation that Peter has (along with the other disciples) been chosen to feed and watch over The Shepherd’s sheep (the verb is different from that in the first and third statements, again in order to prevent monotony).
