'Years' in the Bible

He laid hold of the Dragon--the ancient serpent--who is the Devil and the Adversary, and bound him for a thousand years, and hurled him into the bottomless pit.

He closed the entrance and put a seal upon him in order that he might be unable to lead the nations astray any more until the thousand years were at an end. Afterwards he is to be set at liberty for a short time.

And I saw thrones, and some who were seated on them, to whom judgment was entrusted. And I saw the souls of those who had been beheaded on account of the testimony that they had borne to Jesus and on account of God's Message, and also the souls of those who had not worshipped the Wild Beast or his statue, nor received his mark on their foreheads or on their hands; and they came to Life and were kings with Christ for a thousand years.

No one else who was dead rose to Life until the thousand years were at an end. This is the First Resurrection.

Blessed and holy are those who share in the First Resurrection. The Second Death has no power over them, but they shall be priests to God and to Christ, and shall be kings with Christ for the thousand years.

But when the thousand years are at an end, the Adversary will be released from his imprisonment,
