Revelation 7:13

Revelation 7:13. And one of the elders answered, saying unto me, What are these which are arrayed in white robes and whence came they?

"And I said unto him, Sir, thou knowest." You see the question was put by an angel, as an answer one of the elders answered. Whom did he answer? Why, John; and what John’s heart was inquiring. He was saying to himself, "Who are these?" And one of the elders was responsive to his heart’s inquiry, and put the same inquiry into words on his behalf.
