I will confirm my covenant as a perpetual covenant between me and you. It will extend to your descendants after you throughout their generations. I will be your God and the God of your descendants after you.
David told the leaders of the Levites to appoint some of their relatives as musicians; they were to play various instruments, including stringed instruments and cymbals, and to sing loudly and joyfully.
Asaph was the leader and Zechariah second in command, followed by Jeiel, Shemiramoth, Jehiel, Mattithiah, Eliab, Benaiah, Obed-Edom, and Jeiel. They were to play stringed instruments; Asaph was to sound the cymbals;
David and the army officers selected some of the sons of Asaph, Heman, and Jeduthun to prophesy as they played stringed instruments and cymbals. The following men were assigned this responsibility:
The trumpeters and musicians played together, praising and giving thanks to the Lord. Accompanied by trumpets, cymbals, and other instruments, they loudly praised the Lord, singing: “Certainly he is good; certainly his loyal love endures!” Then a cloud filled the Lord’s temple.
When the builders established the Lord’s temple, the priests, ceremonially attired and with their clarions, and the Levites (the sons of Asaph) with their cymbals, stood to praise the Lord according to the instructions left by King David of Israel.
And the leaders of the Levites were Hashabiah, Sherebiah, Jeshua son of Kadmiel, and their colleagues, who stood opposite them to offer praise and thanks, one contingent corresponding to the other, as specified by David the man of God.
