If, however, the sacrifice he offers is a vow or a freewill offering, it shall be eaten on the day he presents his sacrifice, but the remainder may be eaten on the next day.
Jewish Publication Society of America Version (JPS1917) - Leviticus 7:16 >But if the sacrifice of his offering be a vow, or a freewill-offering, it shall be eaten on the day that he offereth his sacrifice; and on the morrow that which remaineth of it may be eaten.
