'Secretly' in the Bible

After this, Joseph of Arimathea, a disciple of Jesus (but secretly, because he feared the Jewish leaders), asked Pilate if he could remove the body of Jesus. Pilate gave him permission, so he went and took the body away.

Then they secretly instigated some men to say, "We have heard this man speaking blasphemous words against Moses and God."

But Paul said to the police officers, "They had us beaten in public without a proper trial -- even though we are Roman citizens -- and they threw us in prison. And now they want to send us away secretly? Absolutely not! They themselves must come and escort us out!"

For certain men have secretly slipped in among you -- men who long ago were marked out for the condemnation I am about to describe -- ungodly men who have turned the grace of our God into a license for evil and who deny our only Master and Lord, Jesus Christ.
