'Depths' in the Bible

I sink in deep mire, where there is no standing; I am come into the depths of waters, and the flood overfloweth me.

Deliver me out of the mire, let me not sink; let me be delivered from them that hate me, and out of the depths of waters.

Thou, who hast shewn us many and sore troubles, wilt revive us again, and wilt bring us up again from the depths of the earth;

The waters saw thee, O God, the waters saw thee; they trembled, yea, the depths were troubled:

He clave rocks in the wilderness, and gave them drink as out of the depths, abundantly;

They mount up to the heavens, they go down to the depths; their soul is melted because of trouble;

{A Song of degrees.} Out of the depths do I call upon thee, Jehovah.
