And he appointed certain of the Levites to do the service before the ark of Jehovah, and to celebrate, and to thank and praise Jehovah the God of Israel:

And 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;

Part of them also were appointed over the vessels, and over all the holy instruments, and over the fine flour, and the wine, and the oil, and the frankincense, and the spices.
