Leviticus 7:15
And the flesh of the sacrifice of his peace offerings for thanksgiving shall be eaten the same day that it is offered; he shall not leave any of it until the morning.
And the flesh of the sacrifice of his peace offerings for thanksgiving,.... 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 Deuteronomy 12:11
he shall not leave any of it until the morning; which was ordered to encourage liberality to the priests, Levites, and others, since all must be eaten up before morning: according to the Jewish canons, they might eat it no longer than midnight; by that time it was to be all consumed; and it is said {k}, the wise men made an hedge to the law to keep men from sin.
