1 Chronicles 3:21
And the sons of Hananiah; Pelatiah, and Jesaiah: the sons of Rephaiah, the sons of Arnan, the sons of Obadiah, the sons of Shechaniah. And the sons of Hananiah; Pelatiah, and Jesaiah: the sons of Rephaiah, the sons of Arnan, the sons of Obadiah, the sons of Shechaniah.
The verse belongs to the recorded genealogy of the tribe of Judah, specifically the family line of David, naming descendants in that line. These genealogical records preserved family descent needed after the exile to establish hereditary land ownership and the proper duties of temple service. The record shows the preservation of the records of God's children and the integrity of the tribes.
The genealogy shows that God preserves a faithful record of each person. The Davidic line was kept unbroken because Jesus was to come from Judah and David's family, as prophecy required, since Christ came through that tribe. The verse is part of the long, tedious record of names in Chronicles that is usually considered dry and uninteresting and has largely to do with chronology. Its inclusion shows that Scripture contains material whose value and interest are not equally apparent to every reader, with genealogies engaging scholars studying the origins and distribution of peoples, while spiritual truths are found throughout the Bible.
