1 Chronicles 16:5-9

Asaph the chief, and second to him Zechariah, then Jeiel (Jaaziel), Shemiramoth, Jehiel, Mattithiah, Eliab, Benaiah, Obed-edom, and Jeiel with musical instruments, harps and lyres; also Asaph played loud-sounding cymbals; and Benaiah and Jahaziel the priests blew trumpets continually before the ark of the covenant of God. Then on that day David first entrusted to Asaph and his relatives to give thanks to the LORD [as their chief task]. O give thanks to the LORD, call on His name; Make His deeds known among the peoples. Sing to Him, sing praises to Him; Speak of all His wonders.
