'Depths of the Sea' in the Bible

LORD said, I will bring again from Bashan. I will bring again from the depths of the sea,

Is it not thou who dried up the sea, the waters of the great deep, who made the depths of the sea a way for the redeemed to pass over?

He will again have compassion upon us. He will tread our iniquities under foot, and thou will cast all their sins into the depths of the sea.
