and said to them, You are the heads of the fathers' [houses] of the Levites: 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.
After the arrival of the ark in Jerusalem, David and the people celebrated the event with sacrifices and feasting (25-16:3; see notes on 2 Samuel 6:16-23). David also appointed various officials to lead the worship. The arrangements for singing and music made on this occasion became the basis of Israel’s future organized public worship (4-7).
