Matthew 6:3

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.

And their eyes were opened; and Jesus straitly charged them, saying, See that no man know it.

And saith unto him, See thou say nothing to any man: but go thy way, shew thyself to the priest, and offer for thy cleansing those things which Moses commanded, for a testimony unto them.
