the twenty-four elders will fall down before Him who sits on the throne, and will worship Him who lives forever and ever, and will cast their crowns before the throne, saying,

When He had taken the book, the four living creatures and the twenty-four elders fell down before the Lamb, each one holding a harp and golden bowls full of incense, which are the prayers of the saints.

And the twenty-four elders, who sit on their thrones before God, fell on their faces and worshiped God,

And the twenty-four elders and the four living creatures fell down and worshiped God who sits on the throne saying, “Amen. Hallelujah!”
