2 Chronicles 31:16-19

16beside them that were reckoned by genealogy of males, from three years old and upward, even every one that entered into the house of the LORD, as the duty of every day required, for their service in their charges according to their courses;

17and them that were reckoned by genealogy of the priests by their fathers’ houses, and the Levites from twenty years old and upward, in their charges by their courses;

18and them that were reckoned by genealogy of all their little ones, their wives, and their sons, and their daughters, through all the congregation: for in their set office they sanctified themselves in holiness:

19Also for the sons of Aaron the priests, which were in the fields of the suburbs of their cities, in every several city; there were men that were expressed by name, to give portions to all the males among the priests, and to all that were reckoned by genealogy among the Levites.
