Easton's Bible Dictionary
(1.) The fourth “son” of Japheth (Gen. 10:2), whose descendants settled in Greece, i.e., Ionia, which bears the name of Javan in Hebrew. Alexander the Great is called the “king of Javan” (rendered “Grecia,” Dan. 8:21; 10:20; comp. 11:2; Zech. 9:13). This word was universally used by the nations of the East as the generic name of the Greek race. (2.) A town or district of Arabia Felix, from which the Syrians obtained iron, cassia, and calamus (Ezek. 27:19).

<p>ja'-van (yawan, meaning unknown):</p><p>(1) In Ge 10:2,4 = 1Ch 1:5,7 Septuagint Iouan); Isa 66:19; Eze 27:13 Septuagint Hellas, Greece); Da 8:21 m; 10:20; 11:2; Zec 9:13; Joe 3:6 (Hebrew 4:6) Septuagint hoi Hellenes, i.e. "Greeks"), "son" of Japheth, and "father" of Elisha, Tars, Kittim, and Rodarim, i.e. Rhodes (incorrectly "Dodanim" in Ge 10:4). Javan is the Greek Iaon or Ia(v)on, and in Ge and 1Ch = the Ionian Greeks of Asia Minor, probably here = Cyprus. The reference in Eze 27:13 (from which that in Isa 66:19 is copied) is the country personified. In Joe the plural yewanim, is found. In Da the name is extended to the Greeks generally. Corroboration of the name is found in Assyrian (Schrader, editor, Keilinschriftliche Bibliothek, II, 43). "The Persian Yauna occurs in the same double reference from the time of Darius; compare Aesch. Persian., 176, 562" (Skinner, Gen, 198). In Egyptian the word is said to be yevan-(n)a; in the Tell el-Amarna Letters Yivana is mentioned as being in the land of Tyre. See HDB, II, 552b.</p><p>(2) Place (Eze 27:19); the name is missing in Septuagint.</p><p>David Francis Roberts</p>
