Luke 9:18-21

Once when Jesus was praying in private and his disciples were with him, he asked them, “Who do the crowds say I am?” They replied, “Some say John the Baptist; others say Elijah; and still others, that one of the prophets of long ago has come back to life.” “But what about you?” he asked. “Who do you say I am?” Peter answered, “God’s Messiah.” Jesus strictly warned them not to tell this to anyone.
