The Israelite`s had a thing with other numbers also didn`t they , as well as the number 3.?
Such as 7 , 10 , 12 , 40 , 144 ,all of which feature in numerous scriptures and prophetic writings.
And the WatchTower publications of Jehovah`s Witnesses has also alluded to its members of the importance of these numbers over time.
7,000 years for 1 Creative day.
7. Heavenly completion
6. Earthly imperfection
10. ? { I forget this one }
etc,etc.
Hence their continued fascination with predicting Armageddon / End of the World / Great tribulation and such.
The six thousand years of human existence was first taught to finish in the late 1800`s and later it was revised to end about October 1975.
Armageddon was first taught to happen in 1914 ,then 1918 .
The resurrection of faithful men of old ,Abraham ,Issac ,and Jacob was supposed to happen in 1925 .
None of which ever happened .
The carrot of the New World Of Paradise is forever dangled in front of the gullible Jehovah`s Witnesses and the threat of everlasting destruction keeps them in check.
Not to mention the threat of losing their family and friends and forever being shunned if they ever leave the J.W. religion .
Which is emotional blackmail.
