Mark 8:28

And he sent him away to his house, saying, Neither go into the town, nor tell it to any in the town.

And Jesus went out, and his disciples, into the towns of Caesarea Philippi: and by the way he asked his disciples, saying unto them, Whom do men say that I am?

And he saith unto them, But whom say ye that I am? And Peter answereth and saith unto him, Thou art the Christ.

And he charged them that they should tell no man of him.
