Region of Gog, the second of the “sons” of Japheth (Gen. 10:2; 1 Chr. 1:5). In Ezekiel (38:2; 39:6) it is the name of a nation, probably some Scythian or Tartar tribe descended from Japheth. They are described as skilled horsemen, and expert in the use of the bow. The Latin father Jerome says that this word denotes “Scythian nations, fierce and innumerable, who live beyond the Caucasus and the Lake Maeotis, and near the Caspian Sea, and spread out even onward to India.” Perhaps the name “represents the Assyrian Mat Gugi, or ‘country of Gugu,’ the Gyges of the Greeks” (Sayce’s Races, etc.).
Magog
Magog turns up in three very different places. In Genesis 10 he is a son of Japheth, listed among the families of the earth after the flood. In Ezekiel 38 the word has become a land: “Son of man, set thy face against Gog, the land of Magog.” In Revelation 20, Gog and Magog stand for nations gathered “to battle” against God’s people. Christians read these passages in different ways, some as history, some as a picture of a final conflict. All agree that the name grows from a family into a symbol of opposition. Ezekiel 38 is the place to begin.
