1 Chronicles 15:16 YLT

¹⁴  And the priests and the Levites sanctify themselves, to bring up the ark of Jehovah, God of Israel;

¹⁵  and sons of the Levites bear the ark of God, as Moses commanded, according to the word of Jehovah, on their shoulder, with staves, above them.

¹⁶  And David saith to the heads of the Levites to appoint their brethren the singers, with instruments of song, psalteries, and harps, and cymbals, sounding, to lift up with the voice for joy.

¹⁷  And the Levites appoint Heman son of Joel, and of his brethren, Asaph son of Berechiah, and of the sons of Merari their brethren, Ethan son of Kushaiah;

¹⁸  and with them their brethren, the seconds 'in rank', Zechariah, Ben, and Jaaziel, and Shemiramoth, and Jehiel, and Unni, Eliab, and Benaiah, and Maaseiah, and Mattithiah, and Elipheleh, and Mikneiah; and Obed-Edom and Jeiel the gatekeepers;
