LEAVEN PART TWO
Leaven has an important place in Judaism because it is appears so many times in Torah where it is generally associated with sins of any kind. The Jewish Encyclopedia discusses it in this link. Christians, not surprisingly, fail to consider leaven seriously in their doctrines except to represent corrupting sin in all its forms. While associating leaven with sin is not a wrong interpretation, it is an incomplete interpretation because sin itself is not understood correctly.

The first fact to recognize is that in both natural and spiritual terms, leaven exists in the context of bread. Knowing that, we find a clue that we must understand bread before we understand leaven.

The second fact to keep in mind regarding leaven is that it can be both good and bad. Many scriptures about eating unleavened bread in ceremonial circumstances strongly indicate that unleavened bread is preferred to leavened bread. Considering that bread symbolizes an offering to God, leavened bread constitutes a bad or unacceptable offering, while unleavened bread is a good or acceptable offering. The fact of double meanings is best portrayed in this scripture:

1 Corinthians 5: It is actually reported that there is immorality among you, and of a kind that is not found even among pagans; for a man is living with his father’s wife. 2 And you are arrogant! Ought you not rather to mourn? Let him who has done this be removed from among you. 3 For though absent in body I am present in spirit, and as if present, I have already pronounced judgment 4 in the name of the Lord Jesus on the man who has done such a thing. When you are assembled, and my spirit is present, with the power of our Lord Jesus, 5 you are to deliver this man to Satan for the destruction of the flesh, that his spirit may be saved in the day of the Lord Jesus. 6 Your boasting is not good. Do you not know that a little leaven leavens the whole lump? 7 Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our paschal lamb, has been sacrificed. 8 Let us, therefore, celebrate the festival, not with the old leaven, the leaven of malice and evil, but with the unleavened bread of sincerity and truth. 9 I wrote to you in my letter not to associate with immoral men; 10 not at all meaning the immoral of this world, or the greedy and robbers, or idolaters, since then you would need to go out of the world. 11 But rather I wrote to you not to associate with any one who bears the name of brother if he is guilty of immorality or greed, or is an idolater, reviler, drunkard, or robber–not even to eat with such a one. 12 For what have I to do with judging outsiders? Is it not those inside the church whom you are to judge? 13 God judges those outside. “Drive out the wicked person from among you.”

Leavened bread as something to be avoided is introduced in the story of Israels flight from bondage in Egypt as reported in these scriptures:

    Exodus 12:1-39: The LORD said to Moses and Aaron in the land of Egypt, 2 “This month shall be for you the beginning of months; it shall be the first month of the year for you. 3 Tell all the congregation of Israel that on the tenth day of this month they shall take every man a lamb according to their fathers’ houses, a lamb for a household; 4 and if the household is too small for a lamb, then a man and his neighbor next to his house shall take according to the number of persons; according to what each can eat you shall make your count for the lamb. 5 Your lamb shall be without blemish, a male a year old; you shall take it from the sheep or from the goats; 6 and you shall keep it until the fourteenth day of this month, when the whole assembly of the congregation of Israel shall kill their lambs in the evening. 7 Then they shall take some of the blood, and put it on the two doorposts and the lintel of the houses in which they eat them. 8 They shall eat the flesh that night, roasted; with unleavened bread and bitter herbs they shall eat it. 9 Do not eat any of it raw or boiled with water, but roasted, its head with its legs and its inner parts. 10 And you shall let none of it remain until the morning, anything that remains until the morning you shall burn. 11 In this manner you shall eat it: your loins girded, your sandals on your feet, and your staff in your hand; and you shall eat it in haste. It is the LORD’s passover. 12 For I will pass through the land of Egypt that night, and I will smite all the first-born in the land of Egypt, both man and beast; and on all the gods of Egypt I will execute judgments: I am the LORD. 13 The blood shall be a sign for you, upon the houses where you are; and when I see the blood, I will pass over you, and no plague shall fall upon you to destroy you, when I smite the land of Egypt. 14 “This day shall be for you a memorial day, and you shall keep it as a feast to the LORD; throughout your generations you shall observe it as an ordinance for ever. 15 Seven days you shall eat unleavened bread; on the first day you shall put away leaven out of your houses, for if any one eats what is leavened, from the first day until the seventh day, that person shall be cut off from Israel. 16 On the first day you shall hold a holy assembly, and on the seventh day a holy assembly; no work shall be done on those days; but what every one must eat, that only may be prepared by you. 17 And you shall observe the feast of unleavened bread, for on this very day I brought your hosts out of the land of Egypt: therefore you shall observe this day, throughout your generations, as an ordinance for ever. 18 In the first month, on the fourteenth day of the month at evening, you shall eat unleavened bread, and so until the twenty-first day of the month at evening. 19 For seven days no leaven shall be found in your houses; for if any one eats what is leavened, that person shall be cut off from the congregation of Israel, whether he is a sojourner or a native of the land. 20 You shall eat nothing leavened; in all your dwellings you shall eat unleavened bread.” 21 Then Moses called all the elders of Israel, and said to them, “Select lambs for yourselves according to your families, and kill the passover lamb. 22 Take a bunch of hyssop and dip it in the blood which is in the basin, and touch the lintel and the two doorposts with the blood which is in the basin; and none of you shall go out of the door of his house until the morning. 23 For the LORD will pass through to slay the Egyptians; and when he sees the blood on the lintel and on the two doorposts, the LORD will pass over the door, and will not allow the destroyer to enter your houses to slay you. 24 You shall observe this rite as an ordinance for you and for your sons for ever. 25 And when you come to the land which the LORD will give you, as he has promised, you shall keep this service. 26 And when your children say to you, ‘What do you mean by this service?’ 27 you shall say, ‘It is the sacrifice of the LORD’s passover, for he passed over the houses of the people of Israel in Egypt, when he slew the Egyptians but spared our houses.'” And the people bowed their heads and worshiped. 28 Then the people of Israel went and did so; as the LORD had commanded Moses and Aaron, so they did. 29 At midnight the LORD smote all the first-born in the land of Egypt, from the first-born of Pharaoh who sat on his throne to the first-born of the captive who was in the dungeon, and all the first-born of the cattle. 30 And Pharaoh rose up in the night, he, and all his servants, and all the Egyptians; and there was a great cry in Egypt, for there was not a house where one was not dead. 31 And he summoned Moses and Aaron by night, and said, “Rise up, go forth from among my people, both you and the people of Israel; and go, serve the LORD, as you have said. 32 Take your flocks and your herds, as you have said, and be gone; and bless me also!” 33 And the Egyptians were urgent with the people, to send them out of the land in haste; for they said, “We are all dead men.” 34 So the people took their dough before it was leavened, their kneading bowls being bound up in their mantles on their shoulders. 35 The people of Israel had also done as Moses told them, for they had asked of the Egyptians jewelry of silver and of gold, and clothing; 36 and the LORD had given the people favor in the sight of the Egyptians, so that they let them have what they asked. Thus they despoiled the Egyptians. 37 And the people of Israel journeyed from Ram’eses to Succoth, about six hundred thousand men on foot, besides women and children. 38 A mixed multitude also went up with them, and very many cattle, both flocks and herds. 39 And they baked unleavened cakes of the dough which they had brought out of Egypt, for it was not leavened, because they were thrust out of Egypt and could not tarry, neither had they prepared for themselves any provisions.

    Deuteronomy 16:1-8: “Observe the month of Abib, and keep the passover to the LORD your God; for in the month of Abib the LORD your God brought you out of Egypt by night. 2 And you shall offer the passover sacrifice to the LORD your God, from the flock or the herd, at the place which the LORD will choose, to make his name dwell there. 3 You shall eat no leavened bread with it; seven days you shall eat it with unleavened bread, the bread of affliction–for you came out of the land of Egypt in hurried flight–that all the days of your life you may remember the day when you came out of the land of Egypt. 4 No leaven shall be seen with you in all your territory for seven days; nor shall any of the flesh which you sacrifice on the evening of the first day remain all night until morning. 5 You may not offer the passover sacrifice within any of your towns which the LORD your God gives you; 6 but at the place which the LORD your God will choose, to make his name dwell in it, there you shall offer the passover sacrifice, in the evening at the going down of the sun, at the time you came out of Egypt. 7 And you shall boil it and eat it at the place which the LORD your God will choose; and in the morning you shall turn and go to your tents. 8 For six days you shall eat unleavened bread; and on the seventh day there shall be a solemn assembly to the LORD your God; you shall do no work on it.

    We see further proscriptions against eating leavened bread in these scriptures.

    The negative aspect of leaven is confirmed again in these New Testament scriptures:

    Matthew 26:26-27 KJV: And as they were eating , Jesus took bread, and blessed it, and brake it, and gave it to the disciples, and said , Take, eat; this is my body. 27 And he took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it;

    COMMENTARY: The context here is the Passover meal that Jesus shared with his disciples before the day of his crucifixion. The bread of this meal is specified in Exodus 12:1-39 where God lays out his commandments regarding Passover.

    Matthew 13:31-35: Another parable he put before them, saying, “The kingdom of heaven is like a grain of mustard seed which a man took and sowed in his field; 32 it is the smallest of all seeds, but when it has grown it is the greatest of shrubs and becomes a tree, so that the birds of the air come and make nests in its branches.” 33 He told them another parable. “The kingdom of heaven is like leaven which a woman took and hid in three measures of flour, till it was all leavened.” 34 All this Jesus said to the crowds in parables; indeed he said nothing to them without a parable. 35 This was to fulfil what was spoken by the prophet: “I will open my mouth in parables, I will utter what has been hidden since the foundation of the world.”

    COMMENTARY: Flour symbolizes people. Old/First Covenant religionists are unleavened bread. The way we see it, the symbolism of leaven should be specifically applied to the sin of Old/First Covenant religion which is the religion of the Pharisees and Saducees that Jesus warned the people about in these scriptures:

    Matthew 16:6-12: Jesus said to them, “Take heed and beware of the leaven of the Pharisees and Sad’ducees.” 7 And they discussed it among themselves, saying, “We brought no bread.” 8 But Jesus, aware of this, said, “O men of little faith, why do you discuss among yourselves the fact that you have no bread? 9 Do you not yet perceive? Do you not remember the five loaves of the five thousand, and how many baskets you gathered? 10 Or the seven loaves of the four thousand, and how many baskets you gathered? 11 How is it that you fail to perceive that I did not speak about bread? Beware of the leaven of the Pharisees and Sad’ducees.” 12 Then they understood that he did not tell them to beware of the leaven of bread, but of the teaching of the Pharisees and Sad’ducees.

    COMMENTARY: The leaven of the Pharisees and Sad’ducees is religion. They create leavened bread (i.e. false teachings) and serve it to religious people who don’t know the difference between Trees of Life and Trees of Knowledge of Good and Evil. Religious people don’t know that God’s written word and God’s spoken word are not the same. The teachings of the Pharisees and Sad’ducees seem to be good food, so religious people consume it, unaware that it leads to spiritual death.

    The teachings of the Pharisees and Sad’ducees are based on the literal words of the Bible. These teachings are sin because they do not speak for God.  Unleavened bread is God’s word spoken by prophets/messiahs whom God anoints with oil to speak for him. People who listen to (i.e. consume) their teachings are satisfied with eternal life.

    Mark 8:13-19: And he left them, and getting into the boat again he departed to the other side. 14 Now they had forgotten to bring bread; and they had only one loaf with them in the boat. 15 And he cautioned them, saying, “Take heed, beware of the leaven of the Pharisees and the leaven of Herod.” 16 And they discussed it with one another, saying, “We have no bread.” 17 And being aware of it, Jesus said to them, “Why do you discuss the fact that you have no bread? Do you not yet perceive or understand? Are your hearts hardened? 18 Having eyes do you not see, and having ears do you not hear? And do you not remember? 19 When I broke the five loaves for the five thousand, how many baskets full of broken pieces did you take up?” They said to him, “Twelve.”

    COMMENTARY: See commentary above about the leavening of the Pharisees. Also see this link for commentary about the feeding of the five thousand.

    Luke 12:1-4: In the meantime, when so many thousands of the multitude had gathered together that they trod upon one another, he began to say to his disciples first, “Beware of the leaven of the Pharisees, which is hypocrisy. 2 Nothing is covered up that will not be revealed, or hidden that will not be known. 3 Therefore whatever you have said in the dark shall be heard in the light, and what you have whispered in private rooms shall be proclaimed upon the housetops. 4 “I tell you, my friends, do not fear those who kill the body, and after that have no more that they can do.
