1 Chronicles 15:14-16

Young's Literal Translation

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.
