16:1 And they brought in the ark of God and set it inside the tent that David had pitched for it, and they offered burnt offerings and peace offerings before God. And when David had finished offering the burnt offerings and the peace offerings, he blessed the people in the name of the Lord and distributed to all Israel, both men and women, to each a loaf of bread, a portion of meat, and a cake of raisins.

Then he appointed some of the Levites as ministers before the ark of the Lord, to invoke, to thank, and to praise the Lord, the God of Israel. Asaph was the chief, and second to him were Zechariah, Jeiel, Shemiramoth, Jehiel, Mattithiah, Eliab, Benaiah, Obed-edom, and Jeiel, who were to play harps and lyres; Asaph was to sound the cymbals, and Benaiah and Jahaziel the priests were to blow trumpets regularly before the ark of the covenant of God.
