'Secret' in the Bible

“I will make justice the measuring lineAnd righteousness the level;Then hail will sweep away the refuge of liesAnd the waters will overflow the secret place.

“I will give you the treasures of darknessAnd hidden wealth of secret places,So that you may know that it is I,The Lord, the God of Israel, who calls you by your name.

“I have not spoken in secret,In some dark land;I did not say to the offspring of Jacob,‘Seek Me in a waste place’;I, the Lord, speak righteousness,Declaring things that are upright.

“Come near to Me, listen to this:From the first I have not spoken in secret,From the time it took place, I was there.And now the Lord God has sent Me, and His Spirit.”

Who sit among graves and spend the night in secret places;Who eat swine’s flesh,And the broth of unclean meat is in their pots.
