You must eat unleavened bread for seven days. On the first day you must remove yeast from your houses. Whoever eats what is leavened from the first day through the seventh day must be cut off from Israel.
Unleavened bread is to be eaten for those seven days. Nothing leavened may be found among you, and no yeast may be found among you in all your territory.
"Do not present the blood for My sacrifice with anything leavened. The sacrifice of the Passover Festival must not remain until morning.
Do not let any of it remain until morning; you must burn up any part of it that does remain until morning.
