The priests and Levites had made themselves clean. Then the Levites killed the Passover lambs for all the people who had returned from captivity, for their relatives the priests, and for themselves.
There were not enough priests to skin all the animals for the burnt offerings. So their relatives the Levites helped them until the work was finished and other priests could be made holy. The Levites had been more careful to make themselves holy for the Lord’s service than the priests.
After this was finished, the Levites prepared meat for themselves and for the priests, the descendants of Aaron. The priests worked until night, offering the burnt offerings and burning the fat of the sacrifices.
The Levite singers from Asaph’s family stood in the places chosen for them by King David, Asaph, Heman, and Jeduthun, the king’s seer. The gatekeepers at each gate did not have to leave their places, because their fellow Levites had prepared everything for them for the Passover.
He is not like the other priests who had to offer sacrifices every day, first for their own sins, and then for the sins of the people. Christ offered his sacrifice only once and for all time when he offered himself.
