Revelation 20:1-3

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.
