2 Chronicles 35:12-14

Names of God Bible

¹² They set aside the burnt offerings to give them to the laypeople according to their family divisions. The laypeople could then present them to Yahweh as written in the Book of Moses. The Levites did the same with the bulls. ¹³ They roasted the Passover lambs according to the directions. They boiled the holy offerings in pots, kettles, and pans and immediately served them to all the people. ¹⁴ Later, they prepared the animals for themselves and for the priests because the priests (Aaron’s descendants) were sacrificing the burnt offerings and the fat until that evening.

So the Levites prepared the animals for themselves and the priests.
