1 Chronicles 15:16 ASV

¹⁴  So the priests and the Levites sanctified themselves to bring up the ark of Jehovah, the God of Israel.

¹⁵  And the children of the Levites bare the ark of God upon their shoulders with the staves thereon, as Moses commanded according to the word of Jehovah.

¹⁶  And David spake to the chief of the Levites to appoint their brethren the singers, with instruments of music, psalteries and harps and cymbals, sounding aloud and lifting up the voice with joy.

¹⁷  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;

¹⁸  and with them their brethren of the second degree, Zechariah, Ben, and Jaaziel, and Shemiramoth, and Jehiel, and Unni, Eliab, and Benaiah, and Maaseiah, and Mattithiah, and Eliphelehu, and Mikneiah, and Obed-edom, and Jeiel, the doorkeepers.
