Revelation 7:9-10

After the vision of these things I looked, and there was a great number of people, so many that no one could count them. They were from every nation, tribe, people, and language of the earth. They were all standing before the throne and before the Lamb, wearing white robes and holding palm branches in their hands. They were shouting in a loud voice, “Salvation belongs to our God, who sits on the throne, and to the Lamb.”
