12 And said to them, You are the heads of the families of the Levites: make yourselves holy, you and your brothers, so that you may take the ark of the Lord, the God of Israel, to the place which I have made ready for it. 13 For because you did not take it at the first, the Lord our God sent punishment on us, because we did not get directions from him in the right way. 14 So the priests and the Levites made themselves holy to take up the ark of the Lord, the God of Israel. 15 And the sons of the Levites took up the ark of God, lifting it by its rods, as the Lord had said to Moses. 16 And David gave orders to the chief of the Levites to put their brothers the music-makers in position, with instruments of music, corded instruments and brass, with glad voices making sounds of joy.
