Thematic Bible: Divided them into four classes

Of these, [David said,] "Twenty-four thousand [are] to direct the work of the house of Yahweh, along with six thousand judges and officials four thousand gatekeepers, [and] four thousand offering praise with the instruments that I have made for praise." And David organized them [in] divisions according to the sons of Levi: to Gershon, Kohath, and Merari.
