The ancient Hebrews knew that leaven was to be kept out of their grain offerings and removed completely from their homes during Passover. The figurative uses of leaven in the New Testament, no less than with the rabbins, reflect the ancient view of it as "corrupt and corrupting," in parts at least, e.g. Galatians indicates that there is a leaven … A little bit of yeast in the dough will make the whole thing rise because the yeast ferments and spreads throughout the entire lump of dough, making it all rise. Rabbinical writers regularly use leaven as a symbol of evil (Lightfoot). Even a small amount of leaven is sufficient to affect an entire lump of dough, and likewise, a little sin will affect an entire church, nation, or the whole of a person's life (Galatians 5:9). In its most basic sense, it is a symbol of corruption, which has a tendency to multiply and spread like yeast. Leaven was excluded because fermentation was an apt symbol of the working of… In the Bible, leaven is often used to represent sin. There is a verse that tells us what sin is. Leaven has been called “the arch-symbol of fermentation, deterioration, and death and, hence, taboo on the altar of blessing and life." That verse is 1 John 3:4 which says, “Sin is the transgression of the law.” Messiah Yahshua never called leaven sin, but he did give us some examples of how he viewed the symbol of leaven. Therefore purge out the old leaven, that you may be a new lump, since you truly are unleavened. The lamb was symbolic of Jesus Christ who died for all of us so that we could have our sins taken away (1 Corinthians 5:7). In the New Testament, leaven and yeast were often a symbol of sin. The apostle Paul referred to leaven in this way when speaking of the corrupting influence of of a sinner in the congregation in anceint Corinth. Perfect Lamb. For indeed Christ, our Passover, was sacrificed for us. 1 Cor 5:6-8. Gal 5:9 A little leaven leavens the whole lump. When leaven is understood as an influence (teaching in Matt. 16:11-12) it becomes clearer why they left the leavening or influence of Egypt behind (Ex. (See New Testament section on leaven as a symbol of sin.) Many people today understand leaven to be a Bible representation of only sin, rather than an alternative meaning Christ gave it as doctrine (Matt. Here, leaven symbolizes sin that defiles the believer and disrupts the church's worship of God. Leaven was a symbol of sin (1 Corinthians 5:8); so unleavened bread, bread without yeast, was symbolic of a sinless life. The Bible does not say why, but most think that it is because leaven spoils and corrupts, making leavened food unsuitable to offer to God. Removing yeast from the house has become symbolic of removing sin. For most people today the biblical metaphor of leaven typifying evil (or sin) is not too hard to understand. Although; this is not exclusive to sin. The first example is found in Matthew 13:33: “the kingdom of heaven is like unto leaven.” In this parable leaven symbolizes sin that corrupts and spreads. Leaven is also a symbol of sin, and the way sin spreads through its host, affecting the entire organism. The Passover lamb was to be an animal without blemish or deformity. Therefore let us keep the feast, not with old leaven, nor with the leaven of malice and wickedness, but with … Now the lame mans legs are unequal so is a self confident mans interpretation of leaven in Mt 13:33 & Luke when he interprets the leaven as the gospel itself which is unequal with the Torah/law which defines leaven for us as evil/sin. 16:11-12). Now when we look at these verses it is clear that Leaven couldn’t be sin because the “Kingdom of Heaven” and the “Kingdom of God” is likened to leaven… Therefore it must be a state of Mind!
