After this I saw, and look! a great crowd, which no man was able to number, out of all nations and tribes and peoples and tongues, standing before the throne and before the Lamb, dressed in white robes; and there were palm branches in their hands. 10And they keep shouting with a loud voice, saying: “Salvation we owe to our God, who is seated on the throne, and to the Lamb.”
.... “These are the ones who come out of the great tribulation, and they have washed their robes and made them white in the blood of the Lamb. 15That is why they are before the throne of God, and they are rendering him sacred service day and night in his temple; and the One seated on the throne will spread his tent over them. 16They will hunger no more nor thirst anymore, neither will the sun beat down on them nor any scorching heat, 17because the Lamb, who is in the midst of the throne, will shepherd them and will guide them to springs of waters of life. And God will wipe out every tear from their eyes.” Rv7:9
