For seven days let your food be unleavened bread; from the first day no leaven is to be seen in your houses: whoever takes bread with leaven in it, from the first till the seventh day, will be cut off from Israel.
And if any of the flesh of the offering or of the bread is over till the morning, let it be burned with fire; it is not to be used for food, for it is holy.
If any man gives his offering as a praise-offering, then let him give with the offering, unleavened cakes mixed with oil and thin unleavened cakes covered with oil and cakes of the best meal well mixed with oil.
For seven days let no leaven be used through all your land; and nothing of the flesh which is put to death in the evening of the first day is to be kept through the night till morning.
