Luke 9:18-20

And it happened, as He was alone praying, that His disciples joined Him, and He asked them, saying, “Who do the crowds say that I am?” So they answered and said, “John the Baptist, but some say Elijah; and others say that one of the old prophets has risen again.” He said to them, “But who do you say that I am?” Peter answered and said, “The Christ of God.”
