Thematic Bible: Conducting the sacred music

also the Levites who were the singers, all of them, even Asaph, Heman, Jeduthun, and their sons and their brethren, arrayed in fine linen, with cymbals and psalteries and harps, stood at the east end of the altar, and with them a hundred and twenty priests sounding with trumpets;) it came to pass, when the trumpeters and singers were as one, to make one sound to be heard in praising and thanking Jehovah; and when they lifted up their voice with the trumpets and cymbals and instruments of music, and praised Jehovah,'saying , For he is good; for his lovingkindness endureth for ever; that then the house was filled with a cloud, even the house of Jehovah,

and four thousand were doorkeepers; and four thousand praised Jehovah with the instruments which I made,'said David , to praise therewith. And David divided them into courses according to the sons of Levi: Gershon, Kohath, and Merari. Of the Gershonites: Ladan and Shimei. read more.
The sons of Ladan: Jehiel the chief, and Zetham, and Joel, three. The sons of Shimei: Shelomoth, and Haziel, and Haran, three. These were the heads of the fathers houses of Ladan. And the sons of Shimei: Jahath, Zina, and Jeush, and Beriah. These four were the sons of Shimei. And Jahath was the chief, and Zizah the second: but Jeush and Beriah had not many sons; therefore they became a fathers house in one reckoning. The sons of Kohath: Amram, Izhar, Hebron, and Uzziel, four. The sons of Amram: Aaron and Moses; and Aaron was separated, that he should sanctify the most holy things, he and his sons, for ever, to burn incense before Jehovah, to minister unto him, and to bless in his name, for ever. But as for Moses the man of God, his sons were named among the tribe of Levi. The sons of Moses: Gershom and Eliezer. The sons of Gershom: Shebuel the chief. And the sons of Eliezer were: Rehabiah the chief; and Eliezer had no other sons; but the sons of Rehabiah were very many. The sons of Izhar: Shelomith the chief. The sons of Hebron: Jeriah the chief, Amariah the second, Jahaziel the third, and Jekameam the fourth. The sons of Uzziel: Micah the chief, and Isshiah the second. The sons of Merari: Mahli and Mushi. The sons of Mahli: Eleazar and Kish. And Eleazar died, and had no sons, but daughters only: and their brethren the sons of Kish took them to wife . The sons of Mushi: Mahli, and Eder, and Jeremoth, three. These were the sons of Levi after their fathers houses, even the heads of the fathers houses of those of them that were counted, in the number of names by their polls, who did the work for the service of the house of Jehovah, from twenty years old and upward. For David said, Jehovah, the God of Israel, hath given rest unto his people; and he dwelleth in Jerusalem for ever: and also the Levites shall no more have need to carry the tabernacle and all the vessels of it for the service thereof. For by the last words of David the sons of Levi were numbered, from twenty years old and upward. For their office was to wait on the sons of Aaron for the service of the house of Jehovah, in the courts, and in the chambers, and in the purifying of all holy things, even the work of the service of the house of God; for the showbread also, and for the fine flour for a meal-offering, whether of unleavened wafers, or of that which is baked in the pan, or of that which is soaked, and for all manner of measure and size; and to stand every morning to thank and praise Jehovah, and likewise at even;
