The Great Multitude in White Robes

Then one of the elders asked me, “These in white robes—who are they, & where did they come from?”
I answered, “Sir, you know.”
And he said, “These are they who have come out of the great tribulation; they have washed their robes & made them white in the blood of the Lamb. Therefore,
“they are before the throne of God and serve him day and night in his temple;
and he who sits on the throne will spread his tent over them.
Never again will they hunger;
never again will they thirst.
The sun will not beat upon them,
nor any scorching heat.
For the Lamb at the center of the throne will be their shepherd;
he will lead them to springs of living water.
And God will wipe away every tear from their eyes.”
Revelation 7:13-17
