'Secretly' in the Bible

Jesus answered him, “I have spoken openly to the world. I always taught in a synagogue and in the temple [area], where all the Jews habitually congregate; and I said nothing in secret.

And after this, Joseph of Arimathea—a disciple of Jesus, but secretly for fear of the Jews—asked Pilate to let him take away the body of Jesus; and Pilate gave him permission. So he came and took away His body.
