Peter began to say (hrcato legein o Petrov). It was hard for Peter to hold in till now. Matthew 19:27 says that "Peter answered" as if the remark was addressed to him in particular. At any rate Peter reminds Jesus of what they had left to follow him, four of them that day by the sea (Mark 1:20; Matthew 4:22; Luke 5:11). It was to claim obedience to this high ideal on their part in contrast with the conduct of the rich young ruler.
