No leaven shall be seen with you in all your territory for seven days, nor shall any of the flesh that you sacrifice on the evening of the first day remain all night until morning.
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.
If he offers it for a thanksgiving, then he shall offer with the thanksgiving sacrifice unleavened loaves mixed with oil, unleavened wafers smeared with oil, and loaves of fine flour well mixed with oil.
Seven days you shall eat unleavened bread. On the first day you shall remove leaven out of your houses, for if anyone eats what is leavened, from the first day until the seventh day, that person shall be cut off from Israel.
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.
