This section mainly discusses the descendants of Kohath, the lineage through which Aaron and later the high priests are traced back to the exile period. The list of high priests confirms the ongoing priestly service of Israel and supports the legitimacy of the Zadokite priesthood (1 Kings 2:26f, 35). The list continues past Numbers 3:17-20, detailing the descendants of Levi and their roles as singers, temple servants, and priests. Finally, it provides a detailed list of Levitical settlements, taken from Genesis 31 and Joshua 21:5-8. The cities mentioned are located within the territories of other tribes.
