1 Chronicles 25:19 records that Hashabiah, along with his sons and brothers, was assigned as the twelfth group in a series of musical divisions, and that this group included twelve members. This verse is part of a list detailing how the musicians serving in the temple were organized for their duties.
The book of 1 Chronicles is describing how King David set up the temple musicians, dividing them into groups for regular service. Here, the focus is on Hashabiah’s group, showing both their order (twelfth) and their number (twelve people). This organization helped ensure that worship in the temple was orderly and that each family had a clear role in the music ministry.
