Revelation 7:9-13

After these things I looked, and behold, a great multitude which no one could count, from every nation and all the tribes, peoples, and languages, standing before the throne and before the Lamb, clothed in white robes, and palm branches were in their hands;

and they *cried out with a loud voice, saying, “Salvation belongs to our God who sits on the throne, and to the Lamb.”

And all the angels were standing around the throne and around the elders and the four living creatures; and they fell on their faces before the throne and worshiped God,

saying, “Amen, blessing, glory, wisdom, thanksgiving, honor, power, and might belong to our God forever and ever. Amen.”

Then one of the elders responded, saying to me, “These who are clothed in the white robes, who are they, and where have they come from?”
