Vayikra 7:16-18

Orthodox Jewish Bible

¹⁶ But if the zevach of his korban be a neder, or a nedavah, it shall be eaten the same day that he offereth his zevach; and on the following day also the remainder of it shall be eaten;

¹⁷ But the remainder of the basar of the zevach on the yom hashelishi shall be burned with eish.

¹⁸ And if any of the basar of the zevach of his shelamim be eaten at all on the yom hashelishi, it shall not be accepted, neither shall it be imputed (credited) unto him that offereth it; it shall be piggul, and the nefesh that eateth of it shall have his avon to bear.
