The Watchtower has been known for over 130 years as a great scriptural cherry-picker. They pick out disparate unrelated verses and combine them to support the wackiest of wacky doctrines.
On the other hand there are many scriptures they ALMOST NEVER address, whether because they contradict WT doctrine or because they simply don't have a clue what they mean or how to spin them to the WT advantage.
One of these is Revelation 19:1 that mentions a "great crowd" "in heaven." The only time it is ever brought up it is dismissed. "Well, obviously this must be a DIFFERENT "great crowd" from Revelation 7:9 because that great crowd is going to live forever on earth," they say. "But 7:9 says they're 'before the throne' and this one says they're 'in heaven' so what makes you think they're on earth?" you ask. They answer, "because they're two different great crowds."
It forces them into an uncomfortable circular argument so they generally avoid Revelation 19:1.
What other scriptures do JWs avoid because it upsets their applecart? Or if there is further discussion of Rev. 19:1, that's cool, too.
