'Deep' in the Bible

He revealeth the deep and secret things: he knoweth what is in the darkness, and the light dwelleth with him.

Now as he was speaking with me, I was in a deep sleep on my face toward the ground: but he touched me, and set me upright.

Yet heard I the voice of his words: and when I heard the voice of his words, then was I in a deep sleep on my face, and my face toward the ground.
