'Sea' in the Bible

and makest men as the fishes of the sea, as the creeping things, that have no ruler over them?

For the earth shall be filled with the knowledge of the glory of Jehovah, as the waters cover the sea.

Was Jehovah displeased with the rivers? Was thine anger against the rivers, Or thy wrath against the sea, That thou didst ride upon thy horses, Upon thy chariots of salvation?

Thou didst tread the sea with thy horses, The heap of mighty waters.
