Sanctify yourselves, both you and your brothers, that you may bring up the ark of Yahweh, the God of Israel, to the place that I have prepared for it. 13 For because you didn’t carry it at first, Yahweh our God made broke out against us, because we didn’t seek him according to the ordinance.” 14 So the priests and the Levites sanctified themselves to bring up the ark of Yahweh, the God of Israel. 15 The children of the Levites bore the ark of God on their shoulders with the poles thereon, as Moses commanded according to the word of Yahweh. 16 David spoke to the chief of the Levites to appoint their brothers the singers, with instruments of music, stringed instruments and harps and cymbals, sounding aloud and lifting up the voice with joy.
