'Yeast' in the Bible

"'Seven days you shall eat unleavened bread; even the first day you shall put away yeast 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.

Seven days shall there be no yeast found in your houses, for whoever eats that which is leavened, that soul shall be cut off from the congregation of Israel, whether he be a foreigner, or one who is born in the land.

Unleavened bread shall be eaten throughout the seven days; and no leavened bread shall be seen with you, neither shall there be yeast seen with you, in all your borders.

"'No meal offering, which you shall offer to Yahweh, shall be made with yeast; for you shall burn no yeast, nor any honey, as an offering made by fire to Yahweh.

That which is left of it Aaron and his sons shall eat. It shall be eaten without yeast in a holy place. They shall eat it in the court of the Tent of Meeting

It shall not be baked with yeast. I have given it as their portion of my offerings made by fire. It is most holy, as the sin offering, and as the trespass offering.

Moses spoke to Aaron, and to Eleazar and to Ithamar, his sons who were left, "Take the meal offering that remains of the offerings of Yahweh made by fire, and eat it without yeast beside the altar; for it is most holy;

You shall bring out of your habitations two loaves of bread for a wave offering made of two tenth parts of an ephah of fine flour. They shall be baked with yeast, for first fruits to Yahweh.

No yeast shall be seen with you in all your borders seven days; neither shall any of the flesh, which you sacrifice the first day at evening, remain all night until the morning.

He spoke another parable to them. "The Kingdom of Heaven is like yeast, which a woman took, and hid in three measures of meal, until it was all leavened."

Jesus said to them, "Take heed and beware of the yeast of the Pharisees and Sadducees."

How is it that you don't perceive that I didn't speak to you concerning bread? But beware of the yeast of the Pharisees and Sadducees."

Then they understood that he didn't tell them to beware of the yeast of bread, but of the teaching of the Pharisees and Sadducees.

He warned them, saying, "Take heed: beware of the yeast of the Pharisees and the yeast of Herod."

Meanwhile, when a multitude of many thousands had gathered together, so much so that they trampled on each other, he began to tell his disciples first of all, "Beware of the yeast of the Pharisees, which is hypocrisy.

It is like yeast, which a woman took and hid in three measures of flour, until it was all leavened."

Your boasting is not good. Don't you know that a little yeast leavens the whole lump?

Purge out the old yeast, that you may be a new lump, even as you are unleavened. For indeed Christ, our Passover, has been sacrificed in our place.

Therefore let us keep the feast, not with old yeast, neither with the yeast of malice and wickedness, but with the unleavened bread of sincerity and truth.

A little yeast grows through the whole lump.
