Leviticus 7:16-18

Young's Literal Translation

¹⁶ `And if the sacrifice of his offering [is] a vow or free-will offering, in the day of his bringing near his sacrifice it is eaten; and on the morrow also the remnant of it is eaten;

¹⁷ and the remnant of the flesh of the sacrifice on the third day with fire is burnt;

¹⁸ and if any of the flesh of the sacrifice of his peace-offerings be really eaten on the third day, it is not pleasing; for him who is bringing it near it is not reckoned; it is an abominable thing, and the person who is eating of it his iniquity doth bear.
