Charles Ellicott Commentary Revelation 7:10

"and they cry with a great voice, saying, Salvation unto our God who sitteth on the throne, and unto the Lamb." — Revelation 7:10 (ASV)

And cried with a loud voice . . .—Better, And they cry with a loud voice, saying, The salvation to our God who sits upon the throne, and to the Lamb.

Their cry, uttered with a loud voice, is the acknowledgment that their salvation—the salvation which they now taste—is due not to themselves, but to their God and to the Lamb.

The salvation here must, I think, be taken in its most comprehensive sense, including every deliverance—from the curse of law, from the power of sin, and from the perils of life.

The explanation in Revelation 7:14 confirms this. (Philippians 3:9.)

This is the voice of rejoicing and salvation which is in the tabernacles of the righteous, when the Lord, who is their strength and song, has become their salvation (Psalms 118:14).

Note the recurrence of the Lamb. They are before the throne and before the Lamb; their salvation is ascribed to God and to the Lamb.
