I like to frequently cross reference different translations of the Bible (usually Douay-Rheims, KJV, NIV, NASB). I've noticed that the older versions (KJV, Douay Rhiems) of the Revelation 7:14 translates as follows:
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 great tribulation; they have washed their robes and made them white in the blood of the Lamb. (emphasis added)
Whereas the newer versions (NIV, NASB) translates this passage:
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. (emphasis added)
It seems to me that this tiny little "the" makes a huge difference in the theological understanding of end times eschatology- especially for those who have a "premillenial" worldview.
What is the reason for this difference in translation?
