1 Ch. 24: The Number of the Priest

1 Chronicles 24:3 "With the help of Zadok a descendant of Eleazar and Ahimelech a descendant of Ithamar, David separated them into divisions for their appointed order of ministering."

Ministering at the temple was a big responsibility, and it needed a big staff. There were 24 families ready to serve, and they drew lots for an order of service. Then there's a genealogy of the priests, which is important. It's good to know who did what. Why? I'm not sure. But there are the names.
