1 Chronicles 16:40-42

New Century Version

⁴⁰ Every morning and evening they offered burnt offerings on the altar of burnt offerings, following the rules written in the Teachings of the Lord, which he had given Israel. ⁴¹ With them were Heman and Jeduthun and other Levites. They were chosen by name to sing praises to the Lord because his love continues forever. ⁴² Heman and Jeduthun also had the job of playing the trumpets and cymbals and other musical instruments when songs were sung to God. Jeduthun’s sons guarded the gates.
