'Revealer' in the Bible

but there is a God in the heavens, a revealer of secrets, and He hath made known to king Nebuchadnezzar that which is to be in the latter end of the days. 'Thy dream and the visions of thy head on thy bed are 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 answered unto Daniel, and said, Of a truth it is, that your God is a God of gods, and a Lord of kings, and a revealer of secrets, seeing thou couldest reveal this secret.
