Leviticus 5:12

And he shall bring it to the priest , and the priest shall take a handful of it as its memorial portion and burn this on the altar , on the Lord ’s food offerings ; it is a sin offering .

They are to bring it to the priest, who shall take a handful of it as a memorial portion and burn it on the altar on top of the food offerings presented to the Lord. It is a sin offering.

Then shall he bring it to the priest, and the priest shall take his handful of it, even a memorial thereof, and burn it on the altar, according to the offerings made by fire unto the Lord : it is a sin offering.
