Luke 9:18-21

18One day Jesus left the crowds to pray alone. Only his disciples were with him, and he asked them, “Who do people say I am?”

19“Well,” they replied, “some say John the Baptist, some say Elijah, and others say you are one of the other ancient prophets risen from the dead.”

20Then he asked them, “But who do you say I am?” Peter replied, “You are the Messiah sent from God!”

21Jesus warned his disciples not to tell anyone who he was.
