Sea, The: (Heb. yam), signifies

1. "the gathering together of the waters," the ocean (Genesis 1:10);
2. a river, as the Nile (Isaiah 19:5), the Euphrates (Isaiah 21:1; Jeremiah 51:36);
3. the Red Sea (Exodus 14:16,27; 15:4, etc.);
4. the Mediterranean (Exodus 23:31; Numbers 34:6,7; Joshua 15:47; Psalm 80:11, etc.);
5. the "sea of Galilee," an inland fresh-water lake, and
6. the Dead Sea or "salt sea" (Genesis 14:3; Numbers 34:3,12, etc.). The word "sea" is used symbolically in Isaiah 60:5, where it probably means the nations around the Mediterranean. In Daniel 7:3, Revelation 13:1 it may mean the tumultuous changes among the nations of the earth.
