John 7:2-5

2 But the feast of the Jews, the feast of tents, was near.

3 So his brothers said to him, Go away from here into Judaea so that your disciples may see the works which you do.

4 Because no man does things secretly if he has a desire that men may have knowledge of him. If you do these things, let yourself be seen by all men.

5 For even his brothers had no belief in him.
