Why did Nebuchadnezzar go crazy?

Answer 1

Judah submitted to Babylonia in 605 BCE, after a period of Egyptian control, but rebelled in 600 BCE, in anticipation of Egyptian assistance. Babylon retook Jerusalem in 597. At this stage, Nebuchadnezzar's interest in Judah was its strategic position between Babylon and Egypt.

There was an insurrection under Zedekiah in 588 BCE. Nebuchadnezzar could scarcely accept a rebellion that would foreshadow the breakup of his empire, and began a two-year siege of Jerusalem, which he destroyed in 586 BCE and then exiled much of the remnant population of Jerusalem.

Answer 2

In Daniel 4 (Please read Daniel 1-6) King Nebuchadnezzar had a dream and asked Daniel (the King addressed him by his Babylonian name) to interpret. Daniel told the King that the time was coming when God would take away his kingdom. In the same chapter we see that one day the King was feeling prideful about ann that had ben accomplished by him; that same hour a vioce told the King what would happen and it did. That same hour the King was removed from men and lived in the fields with the animals for a few years (some say 7 days but the discribtion of the king does not back this up, some claim 7 years others 5-6 yrs) and when he acknowledge God and who HE was the king's sanity returned. SO who caused the King to go insane. - GOD did and God healed him.
