Revelation 20:1–3 (LEB)
Satan Bound for a Thousand Years
20 And I saw an angel descending from heaven, holding the key of the abyss and a great chain in his hand. 2 And he seized the dragon—the ancient serpent, who is the devil and Satan—and bound him for a thousand years, 3 and threw him into the abyss, and shut it and sealed it above him, in order that he could not deceive the nations again until the thousand years are completed. After these things it is necessary for him to be released for a short time.
