John 7:2-5

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

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

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

5 For even his brethren did not believe on him.
