1 Chronicles 23:1-19

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

The Divisions and Duties of the Levites

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. ⁹ The sons of Shimei: Shelomith, and Haziel, and Haran, three. These were the chief fathers of Laadan. ¹⁰ And the sons of Shimei: Jahath, Ziza, and Jeush, and Beriah. These were the four sons of Shimei. ¹¹ And Jahath was the head, and Ziza the second; and Jeush and Beriah had not many sons: as father's house, therefore, they were reckoned as one. ¹² The sons of Kohath: Amram, Jizhar, Hebron, and Uzziel, four. ¹³ The sons of Amram: Aaron and Moses. And Aaron was separated, that he should be hallowed as most holy, he and his sons for ever, to offer before Jehovah, to do service to him, and to bless in his name for ever. ¹⁴ —And as to Moses the man of God, his sons were named of the tribe of Levi. ¹⁵ The sons of Moses: Gershom and Eliezer. ¹⁶ The sons of Gershom: Shebuel the head. ¹⁷ And the sons of Eliezer: Rehabiah the head; and Eliezer had no other sons, but the sons of Rehabiah were very many. ¹⁸ —The sons of Jizhar: Shelomith the head. ¹⁹ The sons of Hebron: Jeriah the head, Amariah the second, Jahaziel the third, and Jekameam the fourth.
