CAB⁽ⁱ⁾ ³ And the Levites numbered themselves from thirty years old and upward; and their number by their polls amounted to thirty-eight thousand men. ⁴ Of the overseers over the works of the house of the Lord there were twenty-four thousand, and there were six thousand scribes and judges; ⁵ and four thousand gatekeepers, and four thousand to praise the Lord with instruments which he made to praise the Lord. ⁶ And David divided them into daily courses, for the sons of Levi, for Gershon, Kohath, and Merari. ⁷ And for the family of Gershon, Laadan, and Shimei. ⁸ The sons of Laadan were Jehiel the chief, Zetham, and Joel — three in all. ⁹ The sons of Shimei were Shelomith, Haziel, and Haran, three in all: these were the chiefs of the families of Laadan. ¹⁰ And to the sons of Shimei were Jahath, Zina, Jeush, and Beriah: these were the four sons of Shimei. ¹¹ And Jahath was the chief, and Zizah the second; but Jeush and Beriah did not multiply sons, and they became only one reckoning according to the house of their father. ¹² The sons of Kohath were Amram, Izhar, Hebron, and Uzziel — four in all. ¹³ The sons of Amram were Aaron and Moses; and Aaron was appointed for the consecration of the most holy things, he and his sons forever, to burn incense before the Lord, to minister and bless in His name forever. ¹⁴ And as for Moses the man of God, his sons were reckoned to the tribe of Levi. ¹⁵ The sons of Moses were Gershon, and Eliezer. ¹⁶ Of the sons of Gershon, Shebuel was the chief. ¹⁷ And the sons of Eliezer were Rehabiah the chief; and Eliezer had no other sons; but the sons of Rehabiah were very greatly multiplied. ¹⁸ Of the sons of Izhar, Shelomith was the chief. ¹⁹ Of the sons of Hebron, Jeriah was the chief, Amariah the second, Jahaziel the third, and Jekameam the fourth. ²⁰ Of the sons of Uzziel, Michah was the chief, and Jesshiah the second. ²¹ The sons of Merari were Mahli and Mushi. The sons of Mahli were Eleazar, and Kish. ²² And Eleazar died, and he had no sons, but daughters. And the sons of Kish, their brethren, took them as wives. ²³ The sons of Mushi were Mahli, Eder, and Jeremoth — three in all. ²⁴ These are the sons of Levi according to the houses of their fathers; chiefs of their families according to their numbering, according to the number of their names, according to their polls, doing the works of service of the house of the Lord, from twenty years old and upward.
