'Secret' in the Bible

that they would desire mercies of the God of the heavens concerning this secret; that Daniel and his companions should not perish with the rest of the wise men of Babylon.

Then was the secret revealed unto Daniel in a night vision. Then Daniel blessed the God of the heavens.

It is he that revealeth the deep and secret things; He knoweth what is in the darkness, and the light dwelleth with him.

Daniel answered in the presence of the king and said, The secret that the king hath demanded cannot the wise men, the magicians, the scribes, the astrologers, shew unto the king;

And as for me, this secret is revealed to me, not by any wisdom that I have more than any living, but to the intent that the interpretation should be made known to the king, and that thou mightest know the thoughts of thy heart.

The king answered Daniel and said, Of a truth it is that your God is the God of gods, and the Lord of kings, and a revealer of secrets, because thou wast able to reveal this secret.

O Belteshazzar, master of the scribes, because I know that the spirit of the holy gods is in thee, and no secret is too hard for thee, tell me the visions of my dream which I have seen, and the interpretation of it.
