Seven days you shall eat unleavened bread; on the first day you shall remove leaven from your houses, for whoever eats leavened bread from the first day until the seventh day shall be cut off from Israel.
If any of the flesh for the ordination or of 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 must not turn any leaven or honey into smoke as an offering by fire to the Lord.
If you offer it for thanksgiving, you shall offer with the thank offering unleavened cakes mixed with oil, unleavened wafers spread with oil, and cakes of choice flour well soaked in oil.
No leaven shall be seen with you in all your territory for seven days, and none of the meat of what you slaughter on the evening of the first day shall remain until morning.
