Revelation 20:1-6  New International Version

The Thousand Years

20 And I saw an angel coming down out of heaven,^(A) having the key^(B) to the Abyss^(C) and holding in his hand a great chain. ² He seized the dragon, that ancient serpent, who is the devil, or Satan,^(D) and bound him for a thousand years.^{(E) 3} He threw him into the Abyss,^(F) and locked and sealed^(G) it over him, to keep him from deceiving the nations^(H) anymore until the thousand years were ended. After that, he must be set free for a short time.

⁴ I saw thrones^(I) on which were seated those who had been given authority to judge.^(J) And I saw the souls of those who had been beheaded^(K) because of their testimony about Jesus^(L) and because of the word of God.^(M) They^[a] had not worshiped the beast^(N) or its image and had not received its mark on their foreheads or their hands.^(O) They came to life and reigned^(P) with Christ a thousand years. ⁵ (The rest of the dead did not come to life until the thousand years were ended.) This is the first resurrection.^{(Q) 6} Blessed^(R) and holy are those who share in the first resurrection. The second death^(S) has no power over them, but they will be priests^(T) of God and of Christ and will reign with him^(U) for a thousand years.
