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.
Thou shalt not eat with it leavened bread: seven days shalt thou eat without leaven the bread of affliction, because thou camest out of Egypt in fear. That thou mayst remember the day of thy coming out of Egypt, all the days of thy life.
And if there remain of the consecrated flesh, or of the bread till the morning, thou shalt burn the remainder with fire. They shall not be eaten, because they are sanctified.
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.
No leaven shall be seen in all thy coasts for seven days: neither shall any of the flesh of that which was sacrificed the first day in the evening remain until morning.
