'Mysteries' in the Bible

I speak to him audibly and in visions, not in mysteries. If he can gaze at the image of the LORD, why aren't you afraid to speak against my servant Moses?"

He reveals mysteries from the darknessand brings the deepest darkness into the light.

I will declare wise sayings;I will speak mysteries from the past—

But there is a God in heaven who reveals mysteries, and He has let King Nebuchadnezzar know what will happen in the last days. Your dream and the visions that came into your mind as you lay in bed were these:

Your Majesty, while you were in your bed, thoughts came to your mind about what will happen in the future. The revealer of mysteries has let you know what will happen.

The king said to Daniel, “Your God is indeed God of gods, Lord of kings, and a revealer of mysteries, since you were able to reveal this mystery.”
