Revelation 7:9-10

7:9 After these things I looked, and here was an enormous crowd that no one could count, made up of persons from every nation, tribe, people, and language, standing before the throne and before the Lamb dressed in long white robes, and with palm branches in their hands. 7:10 They were shouting out in a loud voice,

“Salvation belongs to our God,

to the one seated on the throne, and to the Lamb!”

Revelation 7:14

7:14 So I said to him, “My lord, you know the answer.” Then he said to me, “These are the ones who have come out of the great tribulation. They have washed their robes and made them white in the blood of the Lamb!

Revelation 7:17

7:17 because the Lamb in the middle of the throne will shepherd them and lead them to springs of living water, and God will wipe away every tear from their eyes.”
