1 Chronicles 23:2-24

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

3Now the Levites were numbered from the age of thirty years and above; and the number of individual males was thirty-eight thousand.

4Of these, twenty-four thousand were to look after the work of the house of the Lord, six thousand were officers and judges,

5four thousand were gatekeepers, and four thousand praised the Lord with musical instruments, “which I made,” said David, “for giving praise.”

6Also David separated them into divisions among the sons of Levi: Gershon, Kohath, and Merari.

7Of the Gershonites: Laadan and Shimei.

8The sons of Laadan: the first Jehiel, then Zetham and Joel—three in all.

9The sons of Shimei: Shelomith, Haziel, and Haran—three in all. These were the heads of the fathers’ houses of Laadan.

10And the sons of Shimei: Jahath, Zina, Jeush, and Beriah. These were the four sons of Shimei.

11Jahath was the first and Zizah the second. But Jeush and Beriah did not have many sons; therefore they were assigned as one father’s house.

12The sons of Kohath: Amram, Izhar, Hebron, and Uzziel—four in all.

13The sons of Amram: Aaron and Moses; and Aaron was set apart, he and his sons forever, that he should sanctify the most holy things, to burn incense before the Lord, to minister to Him, and to give the blessing in His name forever.

14Now the sons of Moses the man of God were reckoned to the tribe of Levi.

15The sons of Moses were Gershon and Eliezer.

16Of the sons of Gershon, Shebuel was the first.

17Of the descendants of Eliezer, Rehabiah was the first. And Eliezer had no other sons, but the sons of Rehabiah were very many.

18Of the sons of Izhar, Shelomith was the first.

19Of the sons of Hebron, Jeriah was the first, Amariah the second, Jahaziel the third, and Jekameam the fourth.

20Of the sons of Uzziel, Michah was the first and Jesshiah the second.

21The sons of Merari were Mahli and Mushi. The sons of Mahli were Eleazar and Kish.

22And Eleazar died, and had no sons, but only daughters; and their brethren, the sons of Kish, took them as wives.

23The sons of Mushi were Mahli, Eder, and Jeremoth—three in all.

24These were the sons of Levi by their fathers’ houses—the heads of the fathers’ houses as they were counted individually by the number of their names, who did the work for the service of the house of the Lord, from the age of twenty years and above.
