'Sea' in the Bible

When He set for the sea its boundarySo that the waters would not transgress [the boundaries set by] His command,When He marked out the foundations of the earth—

And you will be [as unsteady] as one who lies down in the middle of the sea,And [as vulnerable to disaster] as one who lies down on the top of a ship’s mast, saying,

The way of an eagle in the air,The way of a serpent on a rock,The way of a ship in the middle of the sea,And the way of a man with a maid.
