The priests and the Levites had purified themselves, every last one, ¹  and they all were ceremonially pure. They sacrificed the Passover lamb for all the exiles, for their colleagues ²  the priests, and for themselves.

All the Levites who were musicians, including Asaph, Heman, Jeduthun, and their sons and relatives, wore linen. They played cymbals and stringed instruments as they stood east of the altar. They were accompanied by 120 priests who blew trumpets.
