'Organized' in the Bible

And David organized them into divisions according to the sons of Levi: Gershon, Kohath, and Merari.

With respect to the descendants of Aaron, classes of service were organized for Nadab, Abihu, Eleazar, and Ithamar, the descendants of Aaron.

Along with Zadok, one of Eleazar's descendants, and Ahimelech, one of Ithamar's descendants, David organized their service according to their assigned responsibilities.
