The chapter begins with the sons of Levi: Gershon, Kohath and Merari. It follows the line of Kohath to Aaron, Moses and Miriam, and from Aaron to Eleazar, Phinehas and the successive priests, down to Jehozadak, who went into exile when the Lord deported Judah and Jerusalem by the hand of Nebuchadnezzar. The families of Gershon, Kohath and Merari are then listed.
The author then tells how David put certain Levites in charge of the singing in the house of the Lord, once the ark had found rest. They ministered with song before the tabernacle until Solomon built the temple, and they served in turns. The three great singers are named: Heman, a descendant of Samuel, of the family of Kohath; Asaph, at his right hand, of Gershon; and Ethan, at his left, of Merari. The other Levites were set apart for the work of the tabernacle.
The chapter goes on to the descendants of Aaron, who offered the sacrifices and the incense and made atonement for Israel as Moses had commanded, and to the line of Zadok. It closes with the cities the people of Israel gave to the Levites, with their pasturelands: Hebron, a city of refuge, went to the priests, though its fields and villages went to Caleb.
