1 Chronicles 23:6-24 New American Bible (Revised Edition) (NABRE)
6 David apportioned them into divisions according to the sons of Levi: Gershon, Kohath, and Merari.
7 To the Gershonites belonged Ladan and Shimei. 8 The sons of Ladan: Jehiel the chief, then Zetham and Joel; three in all. 9 The sons of Shimei were Shelomoth, Haziel, and Haran; three. These were the heads of the families of Ladan. 10 The sons of Shimei were Jahath, Zizah, Jeush, and Beriah; these were the sons of Shimei, four in all. 11 Jahath was the chief and Zizah was second to him; but Jeush and Beriah had few sons, and therefore they were classed as a single family, exercising a single office.
12 The sons of Kohath: Amram, Izhar, Hebron, and Uzziel; four in all. 13 The sons of Amram were Aaron and Moses. Aaron was set apart to be consecrated as most holy, he and his sons forever, to offer sacrifice before the Lord, to minister to him, and to bless in his name forever. 14 As for Moses, however, the man of God, his sons were counted as part of the tribe of Levi. 15 The sons of Moses were Gershom and Eliezer. 16 The sons of Gershom: Shubael the chief. 17 The sons of Eliezer were Rehabiah the chief—Eliezer had no other sons, but the sons of Rehabiah were very numerous. 18 The sons of Izhar: Shelomith the chief. 19 The sons of Hebron: Jeriah, the chief, Amariah, the second, Jahaziel, the third, and Jekameam, the fourth. 20 The sons of Uzziel: Micah, the chief, and Isshiah, the second.
21 The sons of Merari: Mahli and Mushi. The sons of Mahli: Eleazar and Kish. 22 Eleazar died leaving no sons, only daughters; the sons of Kish, their kinsmen, married them. 23 The sons of Mushi: Mahli, Eder, and Jeremoth; three in all.
24 These were the sons of Levi according to their ancestral houses, the family heads as they were enrolled one by one according to their names. They performed the work of the service of the house of the Lord beginning at twenty years of age.
