Hisgalus 20:4-6

And I saw kise'ot (thrones) and they sat on them and authority for mishpat (judgment) was given to them, and I saw the nefashot (souls) of the ones having been beheaded because of their edut (testimony) for Rebbe, Melech HaMoshiach and because of the dvar HASHEM and for those who did not worship the Chayyah [Beast, Anti-Moshiach] nor its Atzav and did not receive the tav (mark) on the metsakh (forehead) and on their yad (hand), and they awakened to Chayyim (Life) and reigned with Moshiach for elef shanim (a thousand years). And the rest of the Mesim did not awaken to Chayyim (Life) until the elef shanim should be completed. This is the Techiyah HaRishonah (First Resurrection). Me'ushar and Kadosh (Blessed and Holy) is the one having a part in the Techiyah HaRishonah. On these ones the Mavet HaSheyni (the Second Death) does not have shilton (authority, samchut), but they will be kohanim of HASHEM and of Moshiach, and will reign with him for elef shanim.
