Another parable he spoke to them: The kingdom of heaven is like to leaven, which a woman took and hid in three measures of meal, until the whole was leavened.
Seven days there shall not be found any leaven in your houses: he that shall eat leavened bread, his soul shall perish out of the assembly of Israel, whether he be a stranger or born in the land.
Thou shalt not offer the blood of my sacrifice upon leaven: neither shall there remain in the morning any thing of the victim of the solemnity of the Phase.
