Javan was born after The Flood, the fourth son of Noah's son Japheth. In the earliest times, Javan's descendants generally settled in what became Greece (Ionia) i.e. in ancient Bible History, the Hebrew word for what is today called Greece was Javan (pronounced in Hebrew as yaw-vawn). Alexander the Great (a photograph of a statue of him is shown below, see also Ancient Empires - Greece) is called the "king of Javan" in the original Hebrew of the Old Testament, however some translations use "Grecia" or "Greece" for the actually-recorded Javan.
Javan, "From these the coastland peoples spread"
The ancestry of Javan:
"These are the generations of the sons of Noah, Shem, Ham, and Japheth; sons were born to them after the flood. The sons of Japheth: Gomer, Magog, Madai, Javan, Tubal, Meshech, and Tiras.
The sons of Gomer: Ashkenaz, Riphath, and Togarmah.
The sons of Javan: Elishah, Tarshish, Kittim, and Dodanim.
From these the coastland peoples spread. These are the sons of Japheth in their lands, each with his own language, by their families, in their nations." (Genesis 10:1-5 RSV)
Although sometimes translated as "Grecia" or "Greece," as with Alexander the Great in the perfectly-accurate Prophecy below (note: Alexander the Great died in his early thirties, without children to succeed him as king; his kingdom was then divided among four of his generals, exactly as prophesied, long before it happened, as written in these verses by the prophet Daniel), the actual word in the Scriptures is Javan:
"And the he-goat is the king of Greece; and the great horn between his eyes is the first king. As for the horn that was broken, in place of which four others arose, four kingdoms shall arise from his nation [see also The Ptolemies and The Seleucids], but not with his power." (Daniel 8:21-22 RSV)
"And now I will show you the truth. Behold, three more kings shall arise in Persia; and a fourth shall be far richer than all of them; and when he has become strong through his riches, he shall stir up all against the kingdom of Greece. Then a mighty king shall arise, who shall rule with great dominion and do according to his will. And when he has arisen, his kingdom shall be broken and divided toward the four winds of heaven [i.e. to Alexander's four generals], but not to his posterity [posterity means children i.e. Alexander had to children to succeed him], nor according to the dominion with which he ruled [after it was divided, it was never the "superpower" that it was before]; for his kingdom shall be plucked up and go to others besides these." (Daniel 11:2-4 RSV)
Other prophetic references to Javan translated as "Greece":
"For behold, in those days and at that time, when I restore the fortunes of Judah and Jerusalem, I will gather all the nations and bring them down to the valley of Jehoshaphat, and I will enter into judgment with them there, on account of my people and my heritage Israel, because they have scattered them among the nations, and have divided up my land, and have cast lots for my people, and have given a boy for a harlot, and have sold a girl for wine, and have drunk it. "What are you to me, O Tyre and Sidon, and all the regions of Philistia? Are you paying me back for something? If you are paying me back, I will requite your deed upon your own head swiftly and speedily. For you have taken my silver and my gold, and have carried my rich treasures into your temples. You have sold the people of Judah and Jerusalem to the Greeks [i.e. original Hebrew of the Scriptures, Javan], removing them far from their own border. But now I will stir them up from the place to which you have sold them, and I will requite your deed upon your own head." (Joel 3:1-7 RSV)
"For I have bent Judah as my bow; I have made Ephraim its arrow. I will brandish your sons, O Zion [see Who, What or Where Is Zion?], over your sons, O Greece [i.e. original Hebrew of the Scriptures, Javan], and wield you like a warrior's sword. Then The Lord will appear over them, and his arrow go forth like lightning; the Lord God will sound the trumpet, and march forth in the whirlwinds of the south." (Zechariah 9:13-14 RSV)
