“And one of the elders answered, saying unto me, What are these which are arrayed in white robes? and whence came they?”
King James Version (KJV)
7:13 And one of the elders - What stands, verses 13 - 17, #Rev 7:13 |- 17 might have immediately followed the tenth verse; but that the praise of the angels, which was at the same time with that of the great multitude, came in between. Answered - He answered St. John's desire to know, not any words that he spoke.
Re 7:13 What are these which are arrayed in white robes? and whence came they? The questions are asked by the elder that he may teach. "These" refer to the vast multitude described in Re 7:9.
