Priests: Services of Offering Sacrifices

Then the LORD called to Moses and spoke to him from the Tent of Meeting, saying,

However, since there were not enough priests to skin all the burnt offerings, their Levite brothers helped them until the work was finished and until the priests had consecrated themselves. For the Levites had been more diligent in consecrating themselves than the priests had been.

And they slaughtered the Passover lambs, while the priests splattered the blood handed to them and the Levites skinned the animals.
