'Yeast' in the Bible

He told them another parable: “The kingdom of heaven is like yeast that a woman took and mixed into 50 pounds of flour until it spread through all of it.”

Then Jesus told them, “Watch out and beware of the yeast of the Pharisees and Sadducees.”

Why is it you don’t understand that when I told you, ‘Beware of the yeast of the Pharisees and Sadducees,’ it wasn’t about bread?”

Then they understood that He did not tell them to beware of the yeast in bread, but of the teaching of the Pharisees and Sadducees.

Then He commanded them: “Watch out! Beware of the yeast of the Pharisees and the yeast of Herod.”

In these circumstances, a crowd of many thousands came together, so that they were trampling on one another. He began to say to His disciples first: “Be on your guard against the yeast of the Pharisees, which is hypocrisy.

It’s like yeast that a woman took and mixed into 50 pounds of flour until it spread through the entire mixture.”

Your boasting is not good. Don’t you know that a little yeast permeates the whole batch of dough?

Clean out the old yeast so that you may be a new batch. You are indeed unleavened, for Christ our Passover has been sacrificed.

Therefore, let us observe the feast, not with old yeast or with the yeast of malice and evil but with the unleavened bread of sincerity and truth.

A little yeast leavens the whole lump of dough.
