And if ought of the flesh of the consecrations, or of the bread, remain to the morning, then you shall burn the remainder with fire: it shall not be eaten, because it is holy.
No meat offering, which you shall bring to the LORD, shall be made with leaven: for you shall burn no leaven, nor any honey, in any offering of the LORD made by fire.
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.
Another parable spoke he to them; The kingdom of heaven is like to leaven, which a woman took, and hid in three measures of meal, till the whole was leavened.
You shall eat no leavened bread with it; seven days shall you eat unleavened bread therewith, even the bread of affliction; for you came forth out of the land of Egypt in haste: that you may remember the day when you came forth out of the land of Egypt all the days of your life.
And there shall be no leavened bread seen with you in all your coast seven days; neither shall there any thing of the flesh, which you sacrificed the first day at even, remain all night until the morning.
