Unfortunately, the Society explains verse 23 this way.
Later
ExilesofJews. About three years later, in the 23rd year of Nebuchadnezzar’s reign, more Jews were taken into exile. (Jer 52:30) This exile probably involved Jews who had fled to lands that were later conquered by the Babylonians. Lending support to this conclusion is the statement of the historian Josephus: "In the fifth year after the sacking of Jerusalem, which was the twenty-third year of the reign of Nebuchadnezzar, Nebuchadnezzar marched against Coele-Syria and, after occupying it, made war both on the Moabites and the Ammanites. Then, after making these nations subject to him, he invaded Egypt in order to subdue it."—JewishAntiquities, X, 181, 182 (ix, 7)
That was a quote from the Insight book p.481, but the AID book has the same wording.
Even though Josephus doesn't mention any Jews being taken captive in this excerpt, my sister will say the Society is correct.
