1 Chronicles 9:33-34

33Some of the Levites were musicians in the temple. The leaders of those clans lived in rooms at the temple. They needed to do their work as musicians during the night, as well as during the day. So they did not have other jobs to do in the temple.

34Those men were the leaders of the Levite clans. Their names are written in the lists of their clans' ancestors. They lived in Jerusalem.
