Leviticus 7:17-19 Modern English Version (MEV)
17 But the remainder of the flesh of the sacrifice on the third day shall be burned up with fire. 18 If any of the flesh of the sacrifice of his peace offerings is eaten at all on the third day, the one eating shall not be accepted, nor shall it be imputed to him who offers it. It shall be contaminated, and the one who eats of it shall bear his iniquity.
19 The flesh that touches any unclean thing shall not be eaten. It shall be burned up with fire. And as for the other flesh, all who are ritually clean can eat of it.
