Revelation 7:
KJV:
13 And one of the elders answered, saying unto me,
What are these which are arrayed in white robes? and whence came they?
14 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.
NKJV:
13 Then one of the elders answered, saying to me,
“Who are these arrayed in white robes, and where did they come from?”
14 And I said to him, “Sir, you know.”
So he said to me, “These are the ones who come out of the great tribulation,
and washed their robes and made them white in the blood of the Lamb.
We see one difference in comparing the translations; the modern version adds the article 'the', changing the meaning to the saints who have gone through great tribulation beginning in Judea shortly after Pentecost, to some future event that people refer to as 'The Great Tribulation", which apparently the Church will not experience if they are gathered before said tribulation. So who are being persecuted during "The Great Tribulation"?
Note: the article 'the' is not in the original. Surely an agenda is afoot.
