'Secret' in the Bible

for no one does anything in secret and himself seeks to be known in public. If thou doest these things, manifest thyself to the world:

But when his brethren had gone up, then he himself also went up to the feast, not openly, but as in secret.

Jesus answered him, I spoke openly to the world; I taught always in the synagogue and in the temple, where all the Jews come together, and in secret I have spoken nothing.
