1 Chronicles 23:1-19

23¹ Now David was old and full of days; and he made his son Solomon king over Israel.

The Divisions and Duties of the Levites

² And he got together all the chiefs of Israel, with the priests and the Levites. ³ And the Levites, all those of thirty years old and over, were numbered; and the number of them, by heads, man by man, was thirty-eight thousand. ⁴ Of these, twenty-four thousand were to be overseers of the work of the house of the Lord, and six thousand were judges and men of authority; ⁵ Four thousand were door-keepers; and four thousand gave praise to the Lord with the instruments which I made, said David, for giving praise. ⁶ And David put them into divisions under the names of the sons of Levi: Gershon, Kohath, and Merari. ⁷ Of the Gershonites: Ladan and Shimei. ⁸ The sons of Ladan: Jehiel the chief, and Zetham and Joel, three. ⁹ The sons of Shimei: Shelomoth and Haziel and Haran, three; these were the heads of the families of Ladan. ¹⁰ And the sons of Shimei: Jahath, Zizah and Jeush and Beriah; these four were the sons of Shimei. ¹¹ Jahath was the chief and Zizah the second; but Jeush and Beriah had only a small number of sons, so they were grouped together as one family. ¹² The sons of Kohath: Amram, Izhar, Hebron, and Uzziel, four. ¹³ The sons of Amram: Aaron and Moses; and Aaron was made separate and holy, he and his sons for ever, for the care of the most holy things and the burning of offerings before the Lord, to do his work and give blessings in his name for ever. ¹⁴ And the sons of Moses, the man of God, were put into the list of the tribe of Levi. ¹⁵ The sons of Moses: Gershom and Eliezer. ¹⁶ The sons of Gershom: Shebuel the first. ¹⁷ And the sons of Eliezer: Rehabiah the first; and Eliezer had no other sons, but Rehabiah had a great number. ¹⁸ The sons of Izhar: Shelomith the first. ¹⁹ The sons of Hebron: Jeriah the first, Amariah the second, Jahaziel the third, and Jekameam the fourth.
