1 Chronicles 23:1-9

1 So when David was old and full of days, he made Solomon, his son, king over Israel.
2 And he gathered together all the princes of Israel, and the priests and the Levites,
3 were numbered from the age of thirty years and upward; and their number by their polls, man by man, was thirty-eight thousand.
4 Of which, twenty-four thousand were to set forward the work of the house of the LORD, and six thousand were officers and judges;
5 moreover, four thousand were porters, and four thousand praised the LORD with the instruments which David had made to praise therewith.
6 And David divided them into courses according to the sons of Levi, namely, Gershon, Kohath, and Merari.
7 The sons of Gershon: Laadan and Shimei.
8 The sons of Laadan: Jehiel, the first, Zetham and Joel, three.
9 The sons of Shimei: Shelomith, Haziel, and Haran, three. These were the chief of the fathers of Laadan.
