'Secrets' in the Bible

But there is a God in heaven, the unveiler of secrets, and he has given to King Nebuchadnezzar knowledge of what will take place in the last days. Your dreams and the visions of your head on your bed are these:

As for you, O King, the thoughts which came to you on your bed were of what will come about after this: and the unveiler of secrets has made clear to you what is to come.

And the king made answer to Daniel and said, Truly, your God is a God of gods and a Lord of kings, and an unveiler of secrets, for you have been able to make this secret clear.
