And the Heathen shall know that I the Lord do sanctify Israel,.... Or the Gentiles, the converted Gentiles, shall observe and take notice of the gracious dealings of God with his people the Jews; that he calls them with an holy calling; implants principles of grace and holiness in them; separates and consecrates them for his service, and enables them to walk holily, soberly, and righteously:
when my sanctuary shall be in the midst of them for evermore; when his worship shall be set up among them; his Gospel shall be preached unto them, and received by them; and his ordinances administered unto them; and which shall continue till the second coming of Christ.

(Ezekiel 36:23).
sanctify Israel--set it apart as holy unto Myself and inviolable (Exodus 19:5-6).
The objections to a literal interpretation of the prophecy are--(1) The ideal nature of the name Gog, which is the root of Magog, the only kindred name found in Scripture or history. (2) The nations congregated are selected from places most distant from Israel, and from one another, and therefore most unlikely to act in concert (Persians and Libyans, &c.). (3) The whole spoil of Israel could not have given a handful to a tithe of their number, or maintained the myriads of invaders a single day (Ezekiel 38:12-13). (4) The wood of their invaders' weapons was to serve for fuel to Israel for seven years! And all Israel were to take seven months in burying the dead! Supposing a million of Israelites to bury each two corpses a day, the aggregate buried in the hundred eighty working days of the seven months would be three hundred sixty millions of corpses! Then the pestilential vapors from such masses of victims before they were all buried! What Israelite could live in such an atmosphere? (5) The scene of the Lord's controversy here is different from that in Isaiah 34:6, Edom, which creates a discrepancy. (But probably a different judgment is alluded to). (6) The gross carnality of the representation of God's dealings with His adversaries is inconsistent with Messianic times. It therefore requires a non-literal interpretation. The prophetical delineations of the divine principles of government are thrown into the familiar forms of Old Testament relations. The final triumph of Messiah's truth over the most distant and barbarous nations is represented as a literal conflict on a gigantic scale, Israel being the battlefield, ending in the complete triumph of Israel's anointed King, the Saviour of the world. It is a prophetical parable [FAIRBAIRN]. However, though the details are not literal, the distinctiveness in this picture, characterizing also parallel descriptions in writers less ideally picturesque than Ezekiel, gives probability to a more definite and generally literal interpretation. The awful desolations caused in Judea by Antiochus Epiphanes, of Syria (1 Maccabees; and PORPHYRY, quoted by JEROME on Ezekiel), his defilement of Jehovah's temple by sacrificing swine and sprinkling the altar with the broth, and setting up the altar of Jupiter Olympius, seem to be an earnest of the final desolations to be caused by Antichrist in Israel, previous to His overthrow by the Lord Himself, coming to reign (compare Daniel. 8:10-26; Daniel 11:21-45; Daniel 12:1; Zac 13:9; Zac 14:2-3). GROTIUS explains Gog as a name taken from Gyges, king of Lydia; and Magog as Syria, in which was a city called Magag [PLINY, 5.28]. What Ezekiel stated more generally, Revelation 20:7-9 states more definitely as to the anti-Christian confederacy which is to assail the beloved city.
