'Twenty four' in the Bible

Surrounding the throne there were also twenty-four other thrones, on which sat twenty-four Elders clothed in white robes, with victors' wreaths of gold upon their heads.

the twenty-four Elders fall down before Him who sits on the throne and worship Him who lives until the Ages of the Ages, and they cast their wreaths down in front of the throne,

And when He had taken the book, the four living creatures and the twenty-four Elders fell down before the Lamb, having each of them a harp and bringing golden bowls full of incense, which represent the prayers of God's people.

Then the twenty-four Elders, who sit on thrones in the presence of God, fell on their faces and worshipped God,

And the twenty-four Elders and the four living creatures fell down and worshipped God who sits upon the throne. "Even so," they said; "Hallelujah!"
