1 Chronicles 23
1 Chronicles 23 is the twenty-third chapter of the Books of Chronicles in the Hebrew Bible or the First Book of Chronicles in the Old Testament of the Christian Bible. The book is compiled from older sources by an unknown person or group, designated by modern scholars as "the Chronicler", and had the final shape established in late fifth or fourth century BCE. This chapter records the divisions and duties of the Levites. The whole chapter belongs to the section focusing on the kingship of David (1 Chronicles 9:35 to 29:30), which from chapter 22 to  the end does not have parallel in 2 Samuel. Text. This chapter was originally written in the Hebrew language. It is divided into 32 verses. Textual witnesses. Some early manuscripts containing the text of this chapter in Hebrew are of the Masoretic Text tradition, which includes the Aleppo Codex (10th century), and Codex Leningradensis (1008). Extant manuscripts of a Koine Greek translation known as the Septuagint, made in the last few centuries BCE, include Codex Vaticanus (B; formula_1; 4th century), Codex Alexandrinus (A; formula_1; 5th century) and Codex Marchalianus (Q; formula_1; 6th century). David organizes the Levites (23:1–24). This section  details David's preparation for his succession as he reached a venerable stage of life, and his priority was to instruct the leaders of Israel, the priests and the Levites, who would help Solomon reigning and building the temple. The census of the Levites (verses 3–5) does not contradict 1 Chronicles 21:6, because it is not a general population census but concerns the division of duties only ascribed to this particular tribe. The Levites are not primarily recorded according to their family trees here, but significantly to their functions: officers and judges, gatekeepers, musicians. They are to be listed further  in 1 Chronicles 23–26. Verse 2. David prepared well for his death and the reign of his successor, Solomon, by convening his officials to achieve a smooth transition (without mentioning the events recorded in 2 Samuel 15–1 Kings 2. The verse parallels 1 Chronicles 28:1 for the latter as a 'resumptive repetition'. although there are apparent differences (cf. 1 Chronicles 13:5 and 15:3 show that repetitions does not always need be 'resumptive'. Verse 3. The minimum age of Levites for holding office varies, perhaps according to the number of people available for the duties: 30 years old and above in  Numbers 4:3, 23, 30, as here; 25 in Numbers 8:24; 20 in Ezra 3:8;1 Chroncles 23:24–27; 2 Chroncles 31:17. Verse 6. The 'tripartite segmentation' of the Levites is similar to that in Exodus 6:16–19; Numbers 3:17–39; 1 Chronicles 6:1, 16–47. The families of these three Levite clans are listed in verses 7–24, resulting 24 courses (Japhet (1993: 43): Gershon 10, Kohath 9, Merari 5) or 22 (Rudolph (1955: 155): Gershon 9, Kohath 9, Merari 4). Each course or division was to perform duties in rotation until a round was completed and a new round was started. Duties of the Levites  (23:25–32). This section covers the duties of the Levites, partly repeating those mentioned in 1 Chronicles 9. The peace granted by YHWH to his people forced changes to be made in the job descriptions (verses 25–26, 28–32) in contrast to Deuteronomy 12:8–12 or 1 Chronicles 22:9.
