'Secrets' in the Bible

And [that He would] show you the secrets of wisdom!For sound wisdom has two sides.Know therefore that God forgets a part of your wickedness and guilt.

Would not God discover this?For He knows the secrets of the heart.

He who goes about as a gossip reveals secrets,But he who is trustworthy and faithful keeps a matter hidden.

He who goes about as a gossip reveals secrets;Therefore do not associate with a gossip [who talks freely or flatters].

but there is a God in heaven who reveals secrets, and He has shown King Nebuchadnezzar what will take place in the latter days (end of days). This was your dream and the vision [that appeared] in your mind while on your bed.

As for you, O king, as you were lying on your bed thoughts came into your mind about what will take place in the future; and He who reveals secrets has shown you what will occur.
