'Mystery' in the Bible

so that they might request compassion from the God of heaven concerning this mystery, so that Daniel and his friends would not be destroyed with the rest of the wise men of Babylon.

Then the mystery was revealed to Daniel in a night vision. Then Daniel blessed the God of heaven;

Daniel answered before the king and said, “As for the mystery about which the king has inquired, neither wise men, conjurers, magicians nor diviners are able to declare it to the king.

But as for me, this mystery has not been revealed to me for any wisdom residing in me more than in any other living man, but for the purpose of making the interpretation known to the king, and that you may understand the thoughts of your mind.

The king answered Daniel and said, “Surely your God is a God of gods and a Lord of kings and a revealer of mysteries, since you have been able to reveal this mystery.”

‘O Belteshazzar, chief of the magicians, since I know that a spirit of the holy gods is in you and no mystery baffles you, tell me the visions of my dream which I have seen, along with its interpretation.
