Proverbs 21:1

God directs both good and evil kings.

God directed King Nebuchadnezzar to destroy Jerusalem. This was a punishment because the people in Jerusalem were very evil (2 Chronicles 36:15-17; Daniel 1:2).

Later, God gave a dream to Nebuchadnezzar. This dream was about the future (Daniel 2:28). Later, when Nebuchadnezzar became proud, God made him humble (Daniel 4:28-34). Afterwards, Nebuchadnezzar wrote, ‘God is always king. He always rules in heaven.’ (Daniel 4:34).

Nebuchadnezzar was an evil king who had served false gods (Daniel 3:5-6). But in the end, he praised the real God (Daniel 4:37).
