'Deep' in the Bible

He is the unveiler of deep and secret things: he has knowledge of what is in the dark, and the light has its living-place with him.

Now while he was talking to me, I went into a deep sleep with my face to the earth: but touching me, he put me on my feet where I had been.

But the sound of his words came to my ears, and on hearing his voice I went into a deep sleep with my face to the earth.
