12 “ ‘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.

16 “ ‘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.
