'Secrets' in the Bible

And show you the secrets of wisdom!For sound wisdom has two sides.Know then that God forgets a part of your iniquity.

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

He who goes about as a talebearer reveals secrets,But he who is trustworthy conceals a matter.

He who goes about as a slanderer reveals secrets,Therefore do not associate with a gossip.
