Leviticus 22:14

Unwittingly. If a man who was not entitled to eat of the holy things did so unwittingly, he thereby trespassed in “the holy things of the Lord,” and came under the rule of ch. 5:15, 16. A priest must ever be on his guard to avoid infractions of this regulation. A married daughter, for instance, might be visiting her parents’ home and be given a portion of food to take home. If it was “holy” she had no right to it. A visitor might be invited to eat with the priest’s family. It might be inconvenient to prepare a separate meal for the visitor only, who must therefore choose from the common meal that which he was permitted to eat. Should he or the host make a mistake, it would constitute a transgression.
