Leviticus 7:17-19

The Voice

¹⁷ But all the meat from the sacrifice left over on the third day is to be burned completely so that none is left. ¹⁸ If any of the leftover meat from the peace offering is eaten on the third day, then the person who offered it will not be accepted and will receive no benefit from the sacrifice. By then it has become foul, and the person who eats from it will bear his guilt and suffer the consequences.

¹⁹ Do not eat meat that comes in contact with any impure thing. Burn it up completely. As for any remaining meat that is pure, people who are ritually clean may eat it.
