No yeast is to be found anywhere in your territory for seven days, and none of the meat you sacrifice in the evening of the first day is to remain until morning.
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.
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 until the seventh day must be cut off from Israel.
He told them another parable: ‘The kingdom of heaven is like leaven that a woman took and mixed into twenty kilograms of flour until all of it was leavened.’
