1 Chronicles 2:8

And the sons of Ethan; Azariah.

The verse names Azariah as a son of Ethan within the genealogy of Judah. Such lists preserved family records and established hereditary descent, which was used after the exile for assigning land and maintaining temple service. The genealogy was carefully preserved, illustrating the preservation of the records of God's children and the integrity of Israel's tribes, with the genealogies of Judah and Levi remaining unbroken until Jesus' first advent. Judah's line is especially important because Christ came through it, recording Jesus' descent from David.

Its inclusion shows that genealogical records belong to Scripture and were preserved for instruction as part of Scripture's riches. The long lists of names may not seem valuable or interesting to everyone, are not as interesting or instructive as the Gospels and certain other passages, and need not be read or memorized as often. The lists can engage people who study the origin and distribution of races.

The Sons of Judah lists name people about whom nothing is known, who lived their lives and passed away as ordinary people, some prosperous and some failures. The verse shows that God remembers them all by name though people forgot them thousands of years ago, which comforts an obscure and downhearted person because God does not change and keeps such a name put away safe and sure in His lists.
