And if any of the flesh for the ordination, or of the bread, remain until the morning, then you shall burn the remainder with fire; it shall not be eaten, because it is holy.
“No cereal offering which you bring to the Lord shall be made with leaven; for you shall burn no leaven nor any honey as an offering by fire to the Lord.
And the flesh of the sacrifice of his peace offerings for thanksgiving shall be eaten on the day of his offering; he shall not leave any of it until the morning.
You shall eat no leavened bread with it; seven days you shall eat it with unleavened bread, the bread of affliction—for you came out of the land of Egypt in hurried flight—that all the days of your life you may remember the day when you came out of the land of Egypt.
No leaven shall be seen with you in all your territory for seven days; nor shall any of the flesh which you sacrifice on the evening of the first day remain all night until morning.
