Revelation 7:9-10, 13-14, 17

After this I saw a vast crowd, too great to count, from every nation and tribe and people and language, standing in front of the throne and before the Lamb. They were clothed in white robes and held palm branches in their hands. And they were shouting with a great roar, “Salvation comes from our God who sits on the throne and from the Lamb!”

Then one of the twenty-four elders asked me, “Who are these who are clothed in white? Where did they come from?” And I said to him, “Sir, you are the one who knows.” Then he said to me, “These are the ones who died in the great tribulation. They have washed their robes in the blood of the Lamb and made them white.

For the Lamb on the throne will be their Shepherd. He will lead them to springs of life-giving water. And God will wipe every tear from their eyes.”
