As the people repopulated Jerusalem, a careful record was kept of the families who took up residence in the city. A central part of this account details the priestly families who moved there. The primary approach among commentators is that the record specifically highlights the priests who settled in Jerusalem, including notable figures like Jedaiah and Jachin.
The family line of Jedaiah presents an interesting detail when compared to parallel historical records. In other accounts, such as the Book of Chronicles, Jedaiah and Joiarib are listed as two entirely separate people. The record here clarifies their true relationship, establishing that Jedaiah was actually the son of Joiarib. Even with this close family tie, Jedaiah was counted and listed in the official records alongside his father as a distinct individual [מלבי״ם].
