Seven days you shall eat unleavened bread. On the first day you shall put away leaven out of your houses, for whoever eats leavened bread from the first day until the seventh day, that person shall be cut off from Israel.
If any of the flesh from the consecrations or from the bread remains until the morning, then you shall burn the remainder with fire. It shall not be eaten, because it is holy.
No grain offering that you bring to the Lord shall be made with leaven, for you shall not burn leaven, nor any honey as a food offering by fire to the Lord.
If he gives it as a thanksgiving offering, then he shall offer with the thanksgiving sacrifice unleavened cakes mixed with oil, and unleavened wafers smeared with oil, and cakes of wheat flour mixed with olive oil.
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.
There must not be any leavened bread seen with you within all your borders for seven days, nor may any of the meat which you sacrificed in the evening on the first day remain overnight until morning.
