Expositor's Bible Commentary 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)

In response to the heavenly Hallels, the twenty-four elders cry out, “Amen, Hallelujah” (cf. comments on 1:7 regarding “Amen” and on 4:4 regarding the elders).
