Revelation

20:4 And I saw thrones, and they sat upon them, and judgment was given unto them: and [I saw] the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received [his] mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
20:5 But the rest of the dead lived not again until the thousand years were finished. This [is] the first resurrection.

Please notice that the Bible has been talking about the first resurrection and that is why it says, "this is the first resurrection".  It is not calling the resurrection of the wicked the "first resurrection".

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.
20:7 And when the thousand years are expired, Satan shall be loosed out of his prison,
