Great Sea is a body of water named in 36 verses of the Bible (Exodus, Numbers, Deuteronomy, Joshua, 1 Kings, 2 Chronicles, Ezra, Psalms, Isaiah, Jeremiah, Ezekiel, Daniel, Joel, Zechariah), shown here on an interactive map. It is identified with the Mediterranean Sea.
The Dead Sea is drawn at its biblical-era extent, one lake including the southern basin; the modern lake has shrunk and split.
