'Deeps' in the Bible

He gathereth the waters of the sea together as a heap: He layeth up the deeps in store-houses.

Thou hast laid me in the lowest pit, In dark places, in the deeps.

Whatsoever Jehovah pleased, that hath he done, In heaven and in earth, in the seas and in all deeps;

Praise Jehovah from the earth, Ye sea-monsters, and all deeps.
