Leviticus 7:11-18 NIV
“ ‘These are the regulations for the fellowship offering anyone may present to the LORD: “ ‘If they offer it as an expression of thankfulness, then along with this thank offering they are to offer thick loaves made without yeast and with olive oil mixed in, thin loaves made without yeast and brushed with oil, and thick loaves of the finest flour well-kneaded and with oil mixed in. Along with their fellowship offering of thanksgiving they are to present an offering with thick loaves of bread made with yeast. They are to bring one of each kind as an offering, a contribution to the LORD; it belongs to the priest who splashes the blood of the fellowship offering against the altar. The meat of their fellowship offering of thanksgiving must be eaten on the day it is offered; they must leave none of it till morning. “ ‘If, however, their offering is the result of a vow or is a freewill offering, the sacrifice shall be eaten on the day they offer it, but anything left over may be eaten on the next day. Any meat of the sacrifice left over till the third day must be burned up. If any meat of the fellowship offering is eaten on the third day, the one who offered it will not be accepted. It will not be reckoned to their credit, for it has become impure; the person who eats any of it will be held responsible.
