Leviticus 22:14
And if a man eat of the holy thing unwittingly, then he shall put the fifth part thereof unto it, and shall give it unto the priest with the holy thing.
And if a man eat of the holy thing unwittingly,.... Either not knowing that it is an holy thing, or the heave offering, or any thing of that kind; or else is ignorant of the punishment of such an action, as Gersom observes; and this is to be understood of any man that was not a priest, or was not of the priest's family, even any common Israelite; so the Targum of Jonathan, a man of Israel, or an Israelite, one of the common people:
then he shall put a fifth part thereof unto it; a fifth part of the value of what he has eaten, to an equivalent for the whole, that is, he shall pay the full value for what he has eaten, and a fifth part besides:
and shall give it to the priest with the holy thing; the meaning is, that he shall give the fifth part to the priest, with the equivalent for what he has eaten; for he could not give the holy thing itself, but a compensation for it; according to Gersom, he was to give the principal to the priest, whose the holy thing was he ate of, and the fifth part he might give to what priest he would. The Jewish canon, concerning this matter, runs thus; he that ignorantly eats the heave offering pays the principal, and the fifth part; and the same, either he that eats, or drinks, or anoints; and whether the heave offering be clean or unclean, he pays the fifth, and the fifth of the fifth; and he does not pay the heave offering but of common things, rightly ordered, and they become an heave offering, and the compensation of it; and if the priest would forgive, he may not {p}.
