Leviticus 7:18-19

It was proper that the sacrificial meat should not be polluted by any approach to putrefaction. But the exclusion of a mean-spirited economy may further have furnished the ground for the distinction between the thank-offerings and the others. The most liberal distribution of the meat of the offering, particularly among the poor who were invited to partake, would plainly be becoming when the sacrifice was intended especially to express gratitude for mercies received.
