Revelation 20:1-3

1Then I saw an angel who was coming down from heaven. He was holding the key to the deep hole. He also held a great chain in his hand.

2He took hold of the dragon. That dragon is the Devil and Satan. He is the snake who has lived since long ago. The angel tied up the dragon with the chain for 1,000 years.

3Then he threw the dragon into the deep hole. He closed the door to the deep hole, and he locked it with the key. He put a seal on the door. During that time, Satan could no longer deceive the people of all nations. But after the 1,000 years have finished, he must go free for a short time.
