'Twenty four' in the Bible
And round the throne twenty-four thrones, and on the thrones twenty-four elders sitting, clothed with white garments; and on their heads golden crowns.
the twenty-four elders shall fall before him that sits upon the throne, and do homage to him that lives to the ages of ages; and shall cast their crowns before the throne, saying,
When the lamb had taken the scroll, the four living creatures and the twenty-four elders bowed down in front of him. Each held a harp and a gold bowl full of incense, the prayers of the saints.
and the four living creatures said, 'Amen!' and the twenty-four elders fell down and they bow before Him who is living to the ages of the ages.
Then the twenty-four elders who were sitting on their thrones in God's presence fell on their faces and worshipped God.
