Revelation 7:11-17

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, “ A men, blessing and glory and wisdom and thanksgiving and honor and power and might, be to our God forever and ever. Amen.” Then one of the elders answered, saying to me, “These who are clothed in the white robes, who are they, and where have they come from?” I said to him, “My lord, you know.” And he said to me, “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. For this reason, they are before the throne of God; and they serve Him day and night in His temple; and He who sits on the throne will spread His tabernacle over them. They will hunger no longer, nor thirst anymore; nor will the sun beat down on them, nor any heat; for the Lamb in the center of the throne will be their shepherd, and will guide them to springs of the water of life; and God will wipe every tear from their eyes.”
