1 Chronicles 23:2-8 Darby Translation 1890 (DARBY)

2. And he gathered together all the princes of Israel, with the priests and the Levites.

3. And the Levites were numbered from thirty years old and upward; and their number, by their polls, man by man, was thirty-eight thousand.

4. Of these, twenty-four thousand were to preside over the work of the house of Jehovah; and six thousand were officers and judges;

5. and four thousand were doorkeepers; and four thousand praised Jehovah with the instruments which I made, said David, to praise therewith.

6. And David divided them into courses according to the sons of Levi: Gershon, Kohath, and Merari.

7. Of the Gershonites: Laadan and Shimei.

8. The sons of Laadan: the head was Jehiel, and Zetham, and Joel, three.
