1 Chronicles 16:37

^14[+] He appointed, according to the ordinance of David his father, the divisions of the priests to their service, and the Levites to their offices, to praise and to minister before the priests, as the duty of every day required, the doorkeepers also by their divisions at every gate, for David the man of God had so commanded.

⁴They kept the feast of booths, as it is written, and offered the daily burnt offerings by number, according to the ordinance, as the duty of every day required;

¹⁷So the Levites appointed Heman the son of Joel; and of his brothers, Asaph the son of Berechiah; and of the sons of Merari their brothers, Ethan the son of Kushaiah; ¹⁸and with them their brothers of the second rank: Zechariah, Ben, Jaaziel, Shemiramoth, Jehiel, Unni, Eliab, Benaiah, Maaseiah, Mattithiah, Eliphelehu, Mikneiah, Obed-Edom, and Jeiel, the doorkeepers. ¹⁹So the singers, Heman, Asaph, and Ethan, were given cymbals of bronze to sound aloud; ²⁰and Zechariah, Aziel, Shemiramoth, Jehiel, Unni, Eliab, Maaseiah, and Benaiah, with stringed instruments set to Alamoth; ²¹and Mattithiah, Eliphelehu, Mikneiah, Obed-Edom, Jeiel, and Azaziah, with harps tuned to the eight-stringed lyre, to lead. ²²Chenaniah, chief of the Levites, was over the singing. He taught the singers, because he was skillful. ²³Berechiah and Elkanah were doorkeepers for the ark. ²⁴Shebaniah, Joshaphat, Nethanel, Amasai, Zechariah, Benaiah, and Eliezer, the priests, blew the trumpets before God’s ark; and Obed-Edom and Jehiah were doorkeepers for the ark.

¹Moreover, David and the captains of the army set apart for the service certain of the sons of Asaph, of Heman, and of Jeduthun, who were to prophesy with harps, with stringed instruments, and with cymbals. The number of those who did the work according to their service was: ²of the sons of Asaph: Zaccur, Joseph, Nethaniah, and Asharelah. The sons of Asaph were under the hand of Asaph, who prophesied at the order of the king. ³Of Jeduthun, the sons of Jeduthun: Gedaliah, Zeri, Jeshaiah, Shimei, Hashabiah, and Mattithiah, six, under the hands of their father Jeduthun, who prophesied in giving thanks and praising the LORD with the harp. ⁴Of Heman, the sons of Heman: Bukkiah, Mattaniah, Uzziel, Shebuel, Jerimoth, Hananiah, Hanani, Eliathah, Giddalti, Romamti-Ezer, Joshbekashah, Mallothi, Hothir, and Mahazioth. ⁵All these were the sons of Heman the king’s seer in the words of God, to lift up the horn. God gave to Heman fourteen sons and three daughters. ⁶All these were under the hands of their father for song in the LORD’s house, with cymbals, stringed instruments, and harps, for the service of God’s house: Asaph, Jeduthun, and Heman being under the order of the king.

⁴He appointed some of the Levites to minister before the LORD’s ark, and to commemorate, to thank, and to praise the LORD, the God of Israel: ⁵Asaph the chief, and second to him Zechariah, then Jeiel, Shemiramoth, Jehiel, Mattithiah, Eliab, Benaiah, Obed-Edom, and Jeiel, with stringed instruments and with harps; and Asaph with cymbals, sounding aloud; ⁶with Benaiah and Jahaziel the priests with trumpets continually, before the ark of the covenant of God.
