Albert Barnes Commentary Revelation 19:4

"And the four and twenty elders and the four living creatures fell down and worshipped God that sitteth on the throne, saying, Amen; Hallelujah." — Revelation 19:4 (ASV)

And the four and twenty elders and the four beasts.

As representatives of the church, and as interested in its welfare, they are now introduced as rejoicing in its final triumph, and in the destruction of its last foe.

Fell down. Prostrated themselves—the usual posture of worship.

And worshipped God that sat on the throne (Revelation 4:2–3, 10). That is, they now adored him for what he had done in delivering the church from all its persecutions, and causing it to triumph in the world.

Saying, Amen.

The word here is expressive of approbation of what God had done; or of their solemn assent to all that had occurred in the destruction of the great enemy of the church.

Alleluia.

The repetition of this word so many times shows the intenseness of the joy of heaven in view of the final triumph of the church.
