Leviticus 7:15

“And the flesh of the sacrifice of his peace offerings for thanksgiving, etc.] Having given directions about the cakes and bread that went along with the peace offerings, offered in thankfulness for mercies received; instructions are next given about eating the flesh of them; and the order is, that that shall be eaten the same day that it is offered; partly by him that brought them, and his family, and partly by the poor he was to invite to eat thereof; and also by the priests and Levites, who were to have their share of it; (see <051211> Deuteronomy 12:11,12,17,18) he shall not leave any of it until the morning; which was ordered to encourage liberality to the priests, Levites, and others,…”

Lev 22:29-30); but that of the vow and freewill-offerings might be eaten on both the first and second days. Whatever remained after that was to be burnt on the third day, i.e., to be destroyed by burning. If any was eaten on the third day, it was not well-pleasing (ירצה "good pleasure," see Lev 1:4), and was "not reckoned to the offerer," sc., as a sacrifice well-pleasing to God; it was "an abomination." פּגּוּל, an abomination, is only applied to the flesh of the sacrifices ( Lev 19:7; Eze 4:14; Isa 65:4), and signifies properly a stench; - compare the…”
