And there shall be no leaven seen with thee in all thy borders seven days. Neither shall any of the flesh, which thou sacrifice the first day at evening, remain all night until the morning.
Unleavened bread shall be eaten throughout the seven days, and there shall no leavened bread be seen with thee, neither shall there be leaven seen with thee in all thy borders.
Seven days ye shall eat unleavened bread, even the first day ye shall put away leaven out of your houses, for whoever eats leavened bread from the first day until the seventh day, that soul shall be cut off from Israel.
He spoke another parable to them. The kingdom of the heavens is like leaven, which having taken, a woman hid in three measures of meal until it was all leavened.
