John 7:2-5

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

3 His brethren therefore said unto him, Depart from this place and go into Judea that thy disciples also may see the works that thou doest.

4 For no one who seeks to be clearly known does anything in secret. If thou doest these things, show thyself to the world.

5 For not even his brethren believed in him.
