Random Bible Question

I finally finished 2 Kings today, but I have a question.

In 2 Kings 24:14 we see that "King Nebuchadnezzar took ten thousand captives from Jerusalem, including all the princes and the best of the soldiers, craftsmen, and smiths. So only the poorest people were left in the land."

In that same chapter, verse 20, we see that "the Lord, in his anger, finally banished the people of Jerusalem and Judah from his presence and sent them into exile."

Then Chapter 25 opens with Jerusalem under siege and verse 21 says, in part, "So the people of Judah were sent into exile from their land."

Then, in verse 26, after the assassination of Zedekiah, "All the people of Judah, from the least to the greatest, as well as the army commanders, fled in panic to Egypt."

My question is, how can Judah be exiled so many times? I understand that not everyone left because it says the poor stuck around, but the rest doesn't make sense to me. I ask because I could see how a non-believer would read this and say, "Hey, this is inconsistent. It keeps telling us they were exiled at different times, under different kings, by different people. If God is all-knowing, and this is His Word, it has to be consistent. They were either exiled at point X or point Y, but not points X, Y, and Z because it never says that they returned between those periods."

Ok. The end. Answers welcomed!
