Revelation 7:10

Revelation 7:10. And cried with a loud voice, saying, Salvation to our God which sitteth upon the throne, and unto the Lamb.

In Jerusalem they cried Hosanna, which was "Save, Lord," but now they have risen a little higher, and they sing, "Salvation to our God." It is the same melody but it is pitched to a loftier key, and there are more to sing it; and they are not now conducting a prince to his throne but they are looking up to the king upon his throne, reigning there.
