The priests killed the bulls first, then the sheep, and then the lambs, and sprinkled the blood of each sacrifice on the altar.

Then the priests killed the goats and poured their blood on the altar as a sacrifice to take away the sin of all the people, for the king had commanded that burnt offerings and sin offerings be made for all Israel.

They took their places in the Temple according to the instructions in the Law of Moses, the man of God. The Levites gave the blood of the sacrifices to the priests, who sprinkled it on the altar.

You shall kill the bull there, and the Aaronite priests shall present the blood to the LORD and then throw it against all four sides of the altar located at the entrance of the Tent.

Then you shall skin the animal and cut it up,

They are to fulfill their duties to you and their responsibilities for the Tent, but they must not have any contact with sacred objects in the Holy Place or with the altar. If they do, both they and you will be put to death.

But you and your sons alone shall fulfill all the responsibilities of the priesthood that concern the altar and what is in the Most Holy Place. These things are your responsibility, because I have given you the gift of the priesthood. Any unqualified person who comes near the sacred objects shall be put to death."

In the same way Moses also sprinkled the blood on the Sacred Tent and over all the things used in worship.

Indeed, according to the Law almost everything is purified by blood, and sins are forgiven only if blood is poured out.

Since there were not enough priests to kill all these animals, the Levites helped them until the work was finished. By then more priests had made themselves ritually clean. (The Levites were more faithful in keeping ritually clean than the priests were.)
