GOG and MAGOG
Gog, whose name signifies roof, or covering, it should seem, was some prince; and Magog not a person, but the kingdom. So that it is Gog, and prince of Magog. Some have thought, that these names are general names for the enemies of the church, because they are spoken of both in Ezekiel's prophecy, and the book of the Revelation by St. John. (Ezekiel 38:1-23 and Revelation 20:1-15) It will well reward the reader to turn to the prophecy of Ezekiel, at the thirty-eighth chapter (Ezekiel 38:1-23, in confirmation of this latter opinion.
The land of unwalled villages, and the people that dwell in the midst of the land, or as the margin of the Bible hath it, the navel of the land, can mean no other than Jerusalem, supposed to be the centre of the earth; and, therefore, the sea that bounds the borders in these parts very properly called the Mediterranean. And let the reader judge for himself how suitable it was, and proper, that when the Lord Jesus came on earth to do away the sin and guilt of all nations, the solemn transaction of his "one all-sufficient sacrifice and obedience unto death" should be set forth in the center of the earth, that like the sun in the midway of the heavens which illumines both east and west; so Christ, the sun of righteousness, might extend the efficacy of his light, and life, and warmth in every direction to his people; and his blood, as from the high altar of his own divine nature, flowing down, might wash away, from the morning of creation to the end of time, the whole of human transgression.
