1 Chronicles 23:1-23

When David was old and full of days, he made Solomon his son king over Israel. David assembled all the leaders of Israel and the priests and the Levites. The Levites, thirty years old and upward, were numbered, and the total was 38,000 men. “Twenty-four thousand of these,” David said, “shall have charge of the work in the house of the LORD, 6,000 shall be officers and judges, 4,000 gatekeepers, and 4,000 shall offer praises to the LORD with the instruments that I have made for praise.” And David organized them in divisions corresponding to the sons of Levi: Gershon, Kohath, and Merari. The sons of Gershon were Ladan and Shimei. The sons of Ladan: Jehiel the chief, and Zetham, and Joel, three. The sons of Shimei: Shelomoth, Haziel, and Haran, three. These were the heads of the fathers’ houses of Ladan. And the sons of Shimei: Jahath, Zina, and Jeush and Beriah. These four were the sons of Shimei. Jahath was the chief, and Zizah the second; but Jeush and Beriah did not have many sons, therefore they became counted as a single father’s house. The sons of Kohath: Amram, Izhar, Hebron, and Uzziel, four. The sons of Amram: Aaron and Moses. Aaron was set apart to dedicate the most holy things, that he and his sons forever should make offerings before the LORD and minister to him and pronounce blessings in his name forever. But the sons of Moses the man of God were named among the tribe of Levi. The sons of Moses: Gershom and Eliezer. The sons of Gershom: Shebuel the chief. The sons of Eliezer: Rehabiah the chief. Eliezer had no other sons, but the sons of Rehabiah were very many. The sons of Izhar: Shelomith the chief. The sons of Hebron: Jeriah the chief, Amariah the second, Jahaziel the third, and Jekameam the fourth. The sons of Uzziel: Micah the chief and Isshiah the second. The sons of Merari: Mahli and Mushi. The sons of Mahli: Eleazar and Kish. Eleazar died having no sons, but only daughters; their kinsmen, the sons of Kish, married them. The sons of Mushi: Mahli, Eder, and Jeremoth, three.
