Revelation 7:11-17

And all the angels were standing around the throne and around the elders and the four living beings. And they fell before the throne with their faces to the ground and worshiped God. They sang, “Amen! Blessing and glory and wisdom and thanksgiving and honor and power and strength belong to our God forever and ever! Amen.” 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. “That is why they stand in front of God’s throne and serve him day and night in his Temple. And he who sits on the throne will give them shelter. They will never again be hungry or thirsty; they will never be scorched by the heat of the sun. 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.”
