Revelation 7:13-15

“Then one of the elders asked me, “These in white robes–who are they, and 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 and made them white in the blood of the Lamb…and he who sits on the throne will spread his tent over them”
