Leviticus 5:12

Then shall he bring it to the priest ,.... The flour just as it was, not kneaded and made into a cake, as appears by what follows:

and the priest shall take his handful of it ; as much of the flour as he could hold in one hand:

even a memorial thereof ; to bring to mind his sin, and the goodness of God in admitting of an offering for it, and forgiving it upon that:

and burn it on the altar, according to the offerings made by fire unto the Lord ; in the same manner as other burnt offerings were made:

it is a sin offering ; or an expiatory sacrifice for sin.
