2 Chronicles 35:13-14

And they cook the passover with fire, according to the ordinance, and the sanctified things they have cooked in pots, and in kettles, and in pans--for all the sons of the people.

And afterward they have prepared for themselves, and for the priests: for the priests, sons of Aaron, are in the offering up of the burnt-offering and of the fat till night; and the Levites have prepared for themselves, and for the priests, sons of Aaron.
