Moreover David and the captains of the host separated to the service of the sons of Asaph, and of Heman, and of Jeduthun, who should prophesy with harps, with psalteries, and with cymbals: and the number of the workmen according to their service was:
After that thou shalt come to the hill of God, where is the garrison of the Philistines: and it shall come to pass, when thou art come thither to the city, that thou shalt meet a company of prophets coming down from the high place with a psaltery, and a tabret, and a pipe, and a harp, before them; and they shall prophesy:
And these are the singers, chief of the fathers of the Levites, who remaining in the chambers were free: for they were employed in that work day and night.
And David spake to the chief of the Levites to appoint their brethren to be the singers with instruments of musick, psalteries and harps and cymbals, sounding, by lifting up the voice with joy.
So the Levites appointed Heman the son of Joel; and of his brethren, Asaph the son of Berechiah; and of the sons of Merari their brethren, Ethan the son of Kushaiah;
And with them Heman and Jeduthun, and the rest that were chosen, who were expressed by name, to give thanks to the Lord, because his mercy endureth for ever;
Of the sons of Asaph; Zaccur, and Joseph, and Nethaniah, and Asarelah, the sons of Asaph under the hands of Asaph, which prophesied according to the order of the king.
Also the Levites which were the singers, all of them of Asaph, of Heman, of Jeduthun, with their sons and their brethren, being arrayed in white linen, having cymbals and psalteries and harps, stood at the east end of the altar, and with them an hundred and twenty priests sounding with trumpets:)
¶ And he appointed, according to the order of David his father, the courses of the priests to their service, and the Levites to their charges, to praise and minister before the priests, as the duty of every day required: the porters also by their courses at every gate: for so had David the man of God commanded.
Also Jehoiada appointed the offices of the house of the Lord by the hand of the priests the Levites, whom David had distributed in the house of the Lord, to offer the burnt offerings of the Lord, as it is written in the law of Moses, with rejoicing and with singing, as it was ordained by David.
And the men did the work faithfully: and the overseers of them were Jahath and Obadiah, the Levites, of the sons of Merari; and Zechariah and Meshullam, of the sons of the Kohathites, to set it forward; and other of the Levites, all that could skill of instruments of musick.
And the singers the sons of Asaph were in their place, according to the commandment of David, and Asaph, and Heman, and Jeduthun the king’s seer; and the porters waited at every gate; they might not depart from their service; for their brethren the Levites prepared for them.
And when the builders laid the foundation of the temple of the Lord, they set the priests in their apparel with trumpets, and the Levites the sons of Asaph with cymbals, to praise the Lord, after the ordinance of David king of Israel.
And both the singers and the porters kept the ward of their God, and the ward of the purification, according to the commandment of David, and of Solomon his son.
¶ And without the inner gate were the chambers of the singers in the inner court, which was at the side of the north gate; and their prospect was toward the south: one at the side of the east gate having the prospect toward the north.
