Well Vanderhoven, people on both sides are ignorant. It is not about Daniel 4.
It is about Jehovah's promise to David that his offspring would sit on his throne to time indefinite. That was leading up to Jesus being king. But Jesus lived and died and did not become king. What gives?
David and Solomon on down were kings in Jerusalem subject to no one but Jehovah's laws. That changed when Jehoiakim became a vassel to Babylon in 607.
That would seem to end Jehovah's promise of the kings in the line of David leading to Christ. But that is where Dan 4 comes in. It says the kingdom would be paused or banded for 7 times or 2520 years. That is not from when Jerusalem was destroyed but when the kings became subject to Babylon in 607, or 606 or 605, (who knows), and that would end in 1914, 1915, 1916, then Jesus would become king.
