Chapter 9 of the First Book of Chronicles in the King James Version (KJV) provides a detailed account of the genealogies and roles of the people of Israel, particularly the tribes of Judah and Benjamin, after their return from exile in Babylon. It begins by listing the genealogies of the people who settled in Jerusalem and other cities in Judah. The chapter mentions the priests, Levites, gatekeepers, singers, and temple servants who resided in Jerusalem and were responsible for the religious duties in the house of the Lord.
