This verse lists the names of four Levites who were appointed by King David to be in charge of the music ministry in the house of the Lord. As part of their sacred duty, they prophesied with lyres, harps, and cymbals, serving alongside their relatives under the direction of their father Jeduthun. The mention of prophesying through music highlights the importance of worship and praise in the spiritual life of the Israelites, demonstrating the connection between music, prophecy, and the presence of God in the temple.
