Revelation 7:9-17 (CSB)

9 After this I looked, and there was a vast multitude from every nation, tribe, people, and language, which no one could number, standing before the throne and before the Lamb. They were clothed in white robes with palm branches in their hands. 10 And they cried out in a loud voice:

Salvation belongs to our God,

who is seated on the throne,

and to the Lamb!

11 All the angels stood around the throne, and along with the elders and the four living creatures they fell facedown before the throne and worshiped God, 12 saying,

Amen! Blessing and glory and wisdom

and thanksgiving and honor

and power and strength

be to our God forever and ever. Amen.

13 Then one of the elders asked me, “Who are these people in white robes, and where did they come from? ”

14 I said to him, “Sir, you know.”

Then he told me: These are the ones coming out of the great tribulation. They washed their robes and made them white in the blood of the Lamb.

15 For this reason they are before the throne of God,

and they serve him day and night in his temple.

The one seated on the throne will shelter them:

16 They will no longer hunger;

they will no longer thirst;

the sun will no longer strike them,

nor will any scorching heat.

17 For the Lamb who is at the center of the throne

will shepherd them;

he will guide them to springs of the waters of life,

and God will wipe away every tear from their eyes.
