Mark Chapter 8:
27 And Jesus went on with his disciples, to the villages of Caesarea Philippi; and on the way he asked his disciples, “Who do men say that I am?” 28 And they told him, “John the Baptist; and others say, Elijah; and others one of the prophets.” 29 And he asked them, “But who do you say that I am?” Peter answered him, “You are the Christ.” 30 And he charged them to tell no one about him.
