'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 the LORD, as the waters cover the sea.

Was the LORD displeased against the rivers? was thine anger against the rivers? was thy wrath against the sea, that thou didst ride upon thine horses and thy chariots of salvation?

Thou didst walk through the sea with thine horses, through the heap of great waters.
