'Sea' in the Bible

when he imposed on the sea his decree that the waters should not pass his commandment, when he appointed the foundations of the earth:

and thou shalt be as he that lieth down in the midst of the sea, and as he that lieth down upon the top of a mast:

The way of an eagle in the heavens, the way of a serpent upon a rock, the way of a ship in the midst of the sea, and the way of a man with a maid.
