Rev 20Rev 20:6 Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
Those that are in the first resurrection, raised just prior to the millennium, will reign with Christ a thousand years, and the second death has no power over them.
Rev 20:5 (But the rest of the dead lived not again until the thousand years were finished.) This is the first resurrection.
The rest of the dead refers to the second resurrection, and those mentioned in Ezekiel 37 who will be fighting with Gog of Magog.
It seems quite clear. Can't understand why you can't see it.
7 And when the thousand years are expired, Satan shall be loosed out of his prison,
8 And shall go out to deceive the nations which are in the four quarters of the earth, Gog, and Magog, to gather them together to battle: the number of whom is as the sand of the sea.
No resurrection there
The living are gathered.
9 And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them.
10 And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.
11 And I saw a great white throne, and him that sat on it, from whose face the earth and the heaven fled away; and there was found no place for them.
12 And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works.
13 And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works.
14 And death and hell were cast into the lake of fire. This is the second death
Resurrection and GWTJ is AFTER THE BATTLE you are referring to.
