7 Bible Verses about Yeast

He told another story: "The kingdom of heaven may be compared to yeast which a woman took and worked into a bushel of flour until it all had risen."

And again He said, "To what may I compare the kingdom of God? It is like yeast which a woman took and hid in a bushel of flour until it all had risen."

Your ground for boasting about such a case is not good. Are you not aware that a little yeast will change the whole lump of dough? You must clean out the old yeast, that you may be a fresh lump, as you are to be free from the old yeast. For our Passover Lamb, Christ, has already been sacrificed. So let us keep our feast, not with old yeast nor with the yeast of vice and wickedness, but with the bread of purity and truth without the yeast.

When the disciples crossed the sea, they forgot to take any bread. And Jesus said to them, "Look out, and keep on guarding yourselves against the yeast of the Pharisees and the Sadducees!" Then they began to discuss it among themselves, and said, "It is because we did not take any bread."read more.
Jesus knew it and said, "Why are you discussing among yourselves the fact that you have no bread? Have you so little faith? Do you not understand yet? Do you not remember the five loaves for the five thousand and how many basketfuls you took up? Nor the seven loaves for the four thousand and how many hamper-basketfuls you took up? How is it that you do not understand that I did not speak to you about bread, when I said, keep on guarding yourselves against the yeast of the Pharisees and the Sadducees?" Then they understood that He meant, guard yourselves not against yeast for bread, but against the teaching of the Pharisees and the Sadducees.

Now they had forgotten to bring any bread; that is, they had only one loaf with them in the boat. Then He kept warning them by saying, "Look out! Keep on guarding yourselves against the yeast of the Pharisees and the yeast of Herod." So they were discussing with one another the fact that they had no bread.read more.
And as He noticed it He said to them, "Why are you discussing the fact that you have no bread? Do you not yet know nor understand? Are your minds so dull? Since you have eyes can you not see with them? Since you have ears can you not hear with them? Do you not remember how many basketfuls of pieces you picked up when I broke the five loaves in pieces for the five thousand?" They said to Him, "Twelve." "And how many hamper-basketfuls of pieces when I broke the seven loaves in pieces for the four thousand?" They said to Him, "Seven." He said to them, "How is it that you do not understand?"

Meanwhile as the people had gathered in tens of thousands, so that they were trampling upon one another, He began to say, first of all, to His disciples: "Beware of the yeast of the Pharisees, that is, hypocrisy. There is nothing covered up that will not be uncovered, nor secret that will not be made known; because what you have spoken in darkness will be heard in the light, and what you have whispered in people's ears, behind closed doors, will be proclaimed from the housetops.

Here is what I am saying to you: If you let yourselves be circumcised, Christ can do you no good. I again insist that if any man lets himself be circumcised, he is under obligation to obey the whole law. You people, whoever you are among you, who try to get into right standing with God, through law have cut yourselves off from Christ, you have missed the way of God's favor.read more.
For we, by the Spirit, are awaiting the hoped-for blessing which our right standing with God will bring us. For in union with Christ Jesus neither circumcision nor lack of it counts for anything; but only faith that is spurred on to action by love. You were running beautifully! Who was it that cut into your way and kept you from obeying the truth? Such persuasion never came from Him who called you. A little yeast will transform the whole dough. By our union with the Lord I have confidence in you that you will take no other view of the matter. The man who is unsettling you will certainly pay the penalty for it, no matter who it turns out to be. As for me, myself, brothers, if I am still preaching circumcision, why am I still being persecuted? In such a case the hindrance done by the cross has presumably ceased! I almost wish that these men who are upsetting you would go all the way, and have themselves mutilated.
