These are They (Rev 7:13,14)

"And one of the elders answered, saying unto me,

Who are these, clothed in white robes,

and where have they come?

And I said unto him, Sir, thou knowest.

And he said to me, These are they which came out of great tribulation,

and have washed their robes, and made them white in the blood of the Lamb."
