After Peter's first reply, "You know I love You," what did Jesus tell him in John 21?

Answer: Feed My lambs

After breakfast by the sea, Jesus asked Peter if he loved Him more than these, and then said, "Feed My lambs."

“When they had finished eating, Jesus asked Simon Peter, “Simon son of John, do you love Me more than these?” “Yes, Lord,” he answered, “You know I love You.” Jesus replied, “Feed My lambs.””— John 21:15 (BSB)
