The Great Sea
In English translations of the Holy Scriptures, the "Great Sea" is the term used for the Mediterranean Sea. It's a very accurate translation of the two original Hebrew words of the Bible, pronounced gaw-dole, meaning great, and yawm, which, although literally means to roar, was commonly used to refer to the sea, as in the mighty sound of pounding surf of a great body of water. The Great Sea was of course the western boundary of the land of Israel, but is also referred to in Prophecy regarding the successive Bible-related empires that have, and will have, existed right from ancient times to the day of Christ's return.
"I saw in my vision by night, and, behold, the four winds of the heaven strove upon the great sea"
The Great Sea was, and is, the western boundary of the land of Israel:
"And The Lord [see YHVH, Adonai, Jehovah, LORD] spake unto Moses [see also The Education Of Moses], saying, Command the children of Israel, and say unto them, When ye come into The Land Of Canaan; this is the land that shall fall unto you for an inheritance, even the land of Canaan with the coasts thereof:"
"Then your south quarter shall be from the wilderness of Zin along by the coast of Edom, and your south border shall be the outmost coast of the salt sea eastward: And your border shall turn from the south to the ascent of Akrabbim, and pass on to Zin: and the going forth thereof shall be from the south to Kadeshbarnea, and shall go on to Hazaraddar, and pass on to Azmon: And the border shall fetch a compass from Azmon unto the river of Egypt, and the goings out of it shall be at the sea."
"And as for the western border, ye shall even have the great sea for a border: this shall be your west border."
"And this shall be your north border: from the great sea ye shall point out for you mount Hor: From mount Hor ye shall point out your border unto the entrance of Hamath; and the goings forth of the border shall be to Zedad: And the border shall go on to Ziphron, and the goings out of it shall be at Hazarenan: this shall be your north border."
"And ye shall point out your east border from Hazarenan to Shepham: And the coast shall go down from Shepham to Riblah, on the east side of Ain; and the border shall descend, and shall reach unto the side of the sea of Chinnereth eastward: And the border shall go down to Jordan, and the goings out of it shall be at the salt sea: this shall be your land with the coasts thereof round about." (Numbers 34:1-12 KJV)
The Prophet Daniel referred to "the great sea" in his prophecy about the four great successive empires of humanity that were directly involved in the course of Bible History - and will not end until the return of Jesus Christ (see the Fact Finder question below).
"Daniel spake and said, I saw in my vision by night, and, behold, the four winds of the heaven strove upon the great sea. And four great beasts came up from the sea, diverse one from another" (Daniel 7:2-3 KJV)
Fact Finder: Who were / are the "four beasts" that Daniel saw rising up out of the "great sea"?
