Leaven (Yeast): Leavened Bread Forbidden: At the Passover Meal

For seven days there must be no leaven found in your houses. If anyone eats something leavened, that person, whether a foreigner or native of the land, must be cut off from the congregation of Israel.

You are not to eat anything leavened; eat unleavened bread in all your homes.”

So Moses told the people, “Remember this day, the day you came out of Egypt, out of the house of slavery; for the LORD brought you out of it by the strength of His hand. And nothing leavened shall be eaten.

Today, in the month of Abib, you are leaving.

Unleavened bread shall be eaten during those seven days. Nothing leavened may be found among you, nor shall leaven be found anywhere within your borders.

You must not offer the blood of My sacrifices with anything leavened, nor may the fat of My feast remain until morning.
