These were the sons of Levi by clans, with the heads of clans as they were enrolled and with a list of their names by heads who carried out the task of avodah in the House of Adonai from 20 years old and upward.

to the kohanim who were genealogically registered by their ancestral houses, as well as to the Levites 20 years old and upward, according to their duties and their divisions.
