Leviticus 7:17

But the remainder of the flesh of the sacrifice on the
third day
What remained of it uneaten on the second day, and was kept till the third:

shall be burnt with fire;
that it might neither corrupt, nor be put to superstitious uses, nor be of any profit in any respect; that so niggardliness and distrust of the care of Providence might be discouraged: perhaps some respect may be had in the type to the resurrection of Christ on the third day, having seen no corruption.
