Leviticus 7:17-19

Young's Literal Translation

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.

¹⁹ `And the flesh which cometh against any unclean thing is not eaten; with fire it is burnt; as to the flesh, every clean one doth eat of the flesh;
