'Secret' in the Bible

And when he had been there three months, because the Jews had made a secret design against him when he was about to take ship for Syria, he made a decision to go back through Macedonia.

And when news was given to me that a secret design was being made against the man, I sent him straight away to you, giving orders to those who are against him to make their statements before you.

For the king has knowledge of these things, to whom I am talking freely; being certain that all this is common knowledge to him; for it has not been done in secret.
