John 7:2-5 KJV

2 Now the Jews' feast of tabernacles was at hand.
3 His brethren therefore said unto him, Depart hence, and go into Judaea, that thy disciples also may see the works that thou doest .
4 For there is no man that doeth any thing in secret, and he himself seeketh to be known openly . If thou do these things, shew thyself to the world.
5 For neither did his brethren believe in him.
