John 7:49

After these things Jesus walked in Galilee: for he would not walk in Jewry, because the Jews sought to kill him.

Now the Jews' feast of tabernacles was at hand.

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

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.
