'Secrets' 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:

Thou, O king, thy thoughts on thy bed have come up concerning that which is to be after this, and the Revealer of secrets hath caused thee to know that which is to be.

The king hath answered 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, since thou hast been able to reveal this secret.'
