'Thousand' in the Bible

Then I looked and heard the voice of many angels in a circle around the throne, as well as the living creatures and the elders. Their number was ten thousand times ten thousand -- thousands times thousands --

Now I heard the number of those who were marked with the seal, one hundred and forty-four thousand, sealed from all the tribes of the people of Israel:

From the tribe of Judah, twelve thousand were sealed, from the tribe of Reuben, twelve thousand, from the tribe of Gad, twelve thousand,

from the tribe of Asher, twelve thousand, from the tribe of Naphtali, twelve thousand, from the tribe of Manasseh, twelve thousand,

from the tribe of Simeon, twelve thousand, from the tribe of Levi, twelve thousand, from the tribe of Issachar, twelve thousand,

from the tribe of Zebulun, twelve thousand, from the tribe of Joseph, twelve thousand, from the tribe of Benjamin, twelve thousand were sealed.

Just then a major earthquake took place and a tenth of the city collapsed; seven thousand people were killed in the earthquake, and the rest were terrified and gave glory to the God of heaven.

Then I looked, and here was the Lamb standing on Mount Zion, and with him were one hundred and forty-four thousand, who had his name and his Father's name written on their foreheads.

and they were singing a new song before the throne and before the four living creatures and the elders. No one was able to learn the song except the one hundred and forty-four thousand who had been redeemed from the earth.

He seized the dragon -- the ancient serpent, who is the devil and Satan -- and tied him up for a thousand years.

The angel then threw him into the abyss and locked and sealed it so that he could not deceive the nations until the one thousand years were finished. (After these things he must be released for a brief period of time.)

Then I saw thrones and seated on them were those who had been given authority to judge. I also saw the souls of those who had been beheaded because of the testimony about Jesus and because of the word of God. These had not worshiped the beast or his image and had refused to receive his mark on their forehead or hand. They came to life and reigned with Christ for a thousand years.

(The rest of the dead did not come to life until the thousand years were finished.) This is the first resurrection.

Blessed and holy is the one who takes part in the first resurrection. The second death has no power over them, but they will be priests of God and of Christ, and they will reign with him for a thousand years.

Now when the thousand years are finished, Satan will be released from his prison
