And it came to pass, as he was alone praying, his disciples were with him: and he asked them, saying, Whom say the people that I am? They answering said, John the Baptist; but some say, Elijah; and others say, that one of the old prophets is risen again. He said unto them, But whom say you that I am? Peter answering said, The Christ of God. (Luke 9:18-20)
