'Secret' in the Bible

I will give you the treasures of darknessand riches from secret places,so that you may know that I, Yahweh,the God of Israel call you by your name.

I have not spoken in secret,somewhere in a land of darkness.I did not say to the descendants of Jacob:Seek Me in a wasteland.I, Yahweh, speak truthfully;I say what is right.

Approach Me and listen to this.From the beginning I have not spoken in secret;from the time anything existed, I was there.”And now the Lord Godhas sent me and His Spirit.

sitting among the graves,spending nights in secret places,eating the meat of pigs,and putting polluted broth in their bowls.
