Divrei HaYamim I 15:12-15 דברי הימים א ט״ו:י״ב-ט״ו

and he said to them, You are the chiefs of the fathers’ houses of the Levites: sanctify yourselves, you and your brethren, that you may bring up the ark of the Lord God of Yisra᾽el to the place that I have prepared for it.

For because you did not do so at first, the Lord our God made a breach upon us, because we did not seek him according to the prescribed form.

So the priests and the Levites sanctified themselves to bring up the ark of the Lord God of Yisra᾽el.

And the children of the Levites bore the ark of God upon their shoulders the bars being upon them, as Moshe had commanded according to the word of the Lord.
