Jeremiah 52:31 - Ellicott's Commentary On The Whole Bible

In the seven and thirtieth year of the captivity of Jehoiachin... — The closing narrative is almost identical with that of 2 Kings 25:27, the only differences being (1) that “five and twentieth” stands for “seven and twentieth,” (2) that in Jeremiah 52:34 we have “the king of Babylon” instead of “the king,” and (3) that the pleonastic words “until the day of his death” are inserted before “all the days of his life.” The reader is referred to the notes on that section. The variations between the two Chapter s, the most important of which have been noticed in the Notes, are not without importance, though insignificant in themselves, as implying that a consistent belief in the substantial truthfulness of the historical records of the Old Testament is independent of mere verbal accordance in matters of minute detail.
