'Mysteries' in the Bible

And he answered and said unto them, Unto you it is given to know the mysteries of the kingdom of heaven, but to them it is not given.

And he said, Unto you it is given to know the mysteries of the kingdom of God: but to the rest in parables; that seeing they may not see, and hearing they may not understand.

Let a man so account of us, as of ministers of Christ, and stewards of the mysteries of God.

And if I have the gift of prophecy, and know all mysteries and all knowledge; and if I have all faith, so as to remove mountains, but have not love, I am nothing.

For he that speaketh in a tongue speaketh not unto men, but unto God; for no man understandeth; but in the spirit he speaketh mysteries.
