'Secret' in the Bible

For no man doeth anything in secret, and himself seeketh to be known openly. If thou doest these things, manifest thyself to the world.

But when his brethren were gone up unto the feast, then went he also up, not publicly, but as it were in secret.

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