And their brothers the Levites were appointed for all the service of the tabernacle of the house of God.

And he appointed certain of the Levites to minister before the ark of LORD, and to celebrate and to thank and praise LORD, the God of Israel:

Some of them were also appointed over the furniture, and over all the vessels of the sanctuary, and over the fine flour, and the wine, and the oil, and the frankincense, and the spices.

So 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.

So the singers, Heman, Asaph, and Ethan, [were appointed] with cymbals of brass to sound aloud.
