Revelation 20:9

And they went up on the breadth of the earth
Either the whole earth, in the several parts of which they will be raised; or the land of Israel, where Christ and his people will be; and so the wicked being raised, will come up from the several parts of the world, and spread themselves over the holy land; just as Gog and Magog are said to cover the land of Israel, as a cloud, ( Ezekiel 38:16 ) and it may be observed, that the very phrase of (Kura bxr) , "the breadth of thy land", is used of Immanuel's land, or the land of Israel, in ( Isaiah 8:8 )

and compassed the camp of the saints about;
these are the blessed and Holy Ones, who have part in the first resurrection, even all the saints; not only the martyrs under the Heathen persecutions, and the confessors of Christ under the Papacy, but all the saints from the beginning of the world; these will be all encamped together, with the tabernacle of God in the midst of them, ( Revelation 21:3 ) and Christ their King at the head of them, ( Micah 2:13 ) the allusion is to the encampment of the children of Israel in the wilderness, about the tabernacle, which was in the midst of them, ( Numbers 2:2 ) &c. afterwards the city of Jerusalem itself was called a camp, and answered in all respects to the camp in the wilderness ^F6, to which the reference is in ( Hebrews 13:11-13 ) and which serves to illustrate the passage here, since it follows:

not material fire; with this the earth, and the bodies of the wicked then upon it, will be burnt at the beginning of the thousand years; but now their bodies will be raised immortal, and not capable of being consumed with such fire; but the fiery indignation of God, or his wrath, which will be poured out like fire, is here meant, which will destroy both body and soul; this is no other than the lake of fire, or second death, into which they will be cast; and which will not be until the judgment is over, though it is here related to show what will be the event and issue of their attack upon the saints: the allusion is to the fire sent upon Gog and Magog, and to the burning of their weapons, in ( Ezekiel 38:22 ) ( Ezekiel 39:6 Ezekiel 39:9 Ezekiel 39:10 ) and so the Jews
