2 Chronicles 35:15

¹⁵ And the singers (the sons of Asaph) stood in their places according to the commandment of David and Asaph and Heman and Jeduthun, the king’s Seer. And the gatekeepers were at every gate, who may not depart from their service. Therefore, their brethren, the Levites, prepared for them.
