'Twenty four' in the Bible

Around the throne there were twenty-four thrones, with twenty-four elders seated on them, clothed in white and with crowns of gold on their heads.

the twenty-four elders fall down before Him who is seated on the throne, and worship Him who lives forever and ever, and they throw their crowns in front of the throne, and say:

When He took it, the four living creatures and the twenty-four elders fell down before the Lamb, each with a harp, and golden bowls that were full of incense, which represent the prayers of God's people.

Then the twenty-four elders who were seated on their thrones before God fell on their faces and worshiped God,

Then the twenty-four elders and the four living creatures fell down and worshiped God who was seated on the throne, saying, "Amen! Praise the Lord!"
