Japheth

Boyd’s Bible Dictionary:

(enlarged). Son of Noah ({vi 138;148;233;256}Gen. 5:32; 6:10; 9:27; 10:21). His generations peopled the “isles of the Gentiles,” and type the Indo-European and Caucasian races ({vi 236-240}Gen. 10:1-5).

Concise Bible Dictionary:

One of three sons of Noah. He was the father of Gomer, Magog, Madai, Javan, Tubal, Meshech, and Tiras. From these names it has been gathered that the descendants of Japheth spread over the whole of Europe and a great part of northern Asia. Noah prophesied of him, “God shall enlarge Japheth, and he shall dwell in the tents of Shem; and Canaan shall be his servant.” He is not here brought into relationship with God, as Shem is: enlargement on the earth is what is predicted, and this has been manifestly fulfilled (Gen. 5:32; Gen. 6:10; Gen. 7:13; {vi 224;229;233}Gen. 9:18,23,27; {vi 236-237;256}Gen. 10:1,2,21; {vi 10257-10258}1 Chron. 1:4-5).
