Exodus
You must eat matzos for seven days, but before the first day you must remove [all] leaven from your homes; for anyone who eats chametz, that soul will be cut off from Yisrael. [Chametz is forbidden] from the first day [of Pesach] until [after] the seventh day.
Leviticus
On the fifteenth day of this month is the festival of matzos, for Adonoy; for seven days you shall eat matzos.
