John 7:2-4

²Now the feast of the Jews, the feast of tabernacles, was at hand.

³His brethren therefore said unto him, Depart hence, and go into Judæa, that thy disciples also may behold thy works which thou doest.

⁴For no man doeth anything in secret, and himself seeketh to be known openly. If thou doest these things, manifest thyself to the world.
