2 Chronicles 29:25

^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.

⁵four thousand were doorkeepers, and four thousand praised the LORD with the instruments which I made for giving praise.”

¹⁵The singers, the sons of Asaph, were in their place, according to the commandment of David, Asaph, Heman, and Jeduthun the king’s seer; and the gatekeepers were at every gate. They didn’t need to depart from their service, because their brothers the Levites prepared for them.

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. ⁷The number of them, with their brothers who were instructed in singing to the LORD, even all who were skillful, was two hundred eighty-eight.

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;

⁴²and with them Heman and Jeduthun with trumpets and cymbals for those that should sound aloud, and with instruments for the songs of God, and the sons of Jeduthun to be at the gate.

¹¹When David rose up in the morning, the LORD’s word came to the prophet Gad, David’s seer, saying,

¹⁶David spoke to the chief of the Levites to appoint their brothers as singers with instruments of music, stringed instruments, harps, and cymbals, sounding aloud and lifting up their voices with joy. 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.

³³These are the singers, heads of fathers’ households of the Levites, who lived in the rooms and were free from other service, for they were employed in their work day and night.

¹²Also the hand of God came on Judah to give them one heart, to do the commandment of the king and of the princes by the LORD’s word.
