2 Chronicles 23:4

This is what you shall do: a third of you, of the priests and Levites who are resuming service on the Sabbath, shall be gatekeepers,

Their relatives in their villages were to come in every seven days from time to time to be with them;

The Levites thirty years old and upward were counted, and their number man by man was 38,000.

David, with Zadok of the sons of Eleazar and Ahimelech of the sons of Ithamar, divided them according to their offices for their assigned duties.

They cast lots, the small (younger) and great (older) alike, in accordance with their fathers’ households, for every gate.

Now it happened while Zacharias was serving as priest before God in the appointed order of his priestly division,
