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 down their crowns before the throne, and say,

When he took the roll, the four animals and the twenty-four elders fell down before the Lamb, each with a harp and gold bowls full of incense, that is, of 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 animals fell down and worshiped God who was seated upon the throne. "Amen!" they said, "Praise the Lord!"
