Mark 8:27-30

Now Jesus and His disciples went out to the towns of Caesarea Philippi; and on the road He asked His disciples, saying to them, “Who do men say that I am?” So they answered, “John the Baptist; but some say, Elijah; and others, one of the prophets.” He said to them, “But who do you say that I am?” Peter answered and said to Him, “You are the Christ.” Then He strictly warned them that they should tell no one about Him.
