Ezra 2:36

The priests. Of the priests, four families with a total of 4,289 men returned to Jerusalem, and three additional families that could not prove their eligibility (vs. 61-63). Three of the legitimate priestly families traced their descent back to persons who had been heads of priestly courses during the reign of David, namely Jedaiah, Immer, and Harim. The other family originated from a certain Pashur, of whom nothing further is known. No Biblical person who bore this name can have been the ancestor of this family.

The four priestly families mentioned in this list of exiles were still the main representatives of the priesthood in Ezra’s time, 80 years later, when all four are mentioned in the list of those who had taken strange wives (Ezra 10:18-22).
