Hi Shepherdless - You'll find when I talk about Maths Virus I am referring not to numbers (arithmetic) but to a mental fog that WT produces using arithmetic. This fog prevents a person from being able to get accurate knowledge.
I do not present a secular date - what I'm saying is that because arithmetic is involved, the bottom line is WT preventing you from calling the number 3, 3 when they want to call 3, 11 (plus a few other issues). In that way it is a secular matter.
The Bible does not say that Jerusalem fell in the 18th year of Nebuchadnezzar anywhere. But it does say it was under seige.
(Jeremiah 52:28-29) . . .These are the people whom Neb‧u‧chad‧rez′zar took into exile: in the seventh year, three thousand and twenty-three Jews. 29 In the eighteenth year of Neb‧u‧chad‧rez′zar, from Jerusalem there were eight hundred and thirty-two souls.
(Jeremiah 32:1-3) . . .The word that occurred to Jeremiah from Jehovah in the tenth year of Zed‧e‧ki′ah the king of Judah, that is, the eighteenth year of Neb‧u‧chad‧rez′zar. 2 And at that time the military forces of the king of Babylon were laying siege to Jerusalem; and as for Jeremiah the prophet, he happened to be under restraint in the Courtyard of the Guard that is in the house of the king of Judah; 3 because Zed‧e‧ki′ah the king of Judah had restrained him,. . .
