King James wording
King James Version
Then understood they how that he bade them not beware of the leaven of bread, but of the doctrine of the Pharisees and of the Sadducees.THE KEY
A teaching is not merely heard; like leaven, it works unseen until it shapes the whole loaf.
THE MEANING
You see that the warning is about the teaching of the Pharisees and Sadducees, not about bread. A teaching can work through your understanding gradually, shaping how the whole appears to you. The verse speaks of doctrine as something that permeates, not just a statement considered on its own.
WHAT THIS UNDOES
It undoes the belief that a teaching is harmless when it sounds respectable or begins as a small influence; what enters can work through the whole.
THE ROOT
ζύμη
zymē
GROWS FROM
ζυμ-
zym-
Leaven or yeast: the fermenting substance that works through dough.
The Greek word points to a fermenting substance that spreads through the dough and changes the whole from within. Jesus identifies the leaven here as teaching, showing how a teaching can permeate understanding rather than remain an isolated idea.
ALSO GROWS
zymoō: To cause to ferment or leaven.
ζυμόω
The related verb makes the image active: leaven works through what it enters, as teaching can work through a person’s understanding.
azymos: Without leaven; unleavened.
ἄζυμος
This contrasting branch shows that the Greek word family distinguishes dough by whether leaven has worked through it.
διδαχή
didachē
GROWS FROM
διδασκ-
didask-
To teach or instruct; διδαχή names teaching or instruction.
The word translated “doctrine” is teaching or instruction: something that forms the hearer, not only a fixed set of claims. Beside leaven, it is pictured as an influence that can move through understanding until it shapes the whole.
ALSO GROWS
didaskō: To teach or instruct.
διδάσκω
This verb shows the action behind the teaching Jesus warns about: instruction enters and forms the hearer.
didaskalos: A teacher or instructor.
διδάσκαλος
The related noun points to the one who gives the teaching, completing the relation between instruction and the person formed by it.
THE PATTERN
A small influence can permeate and shape a whole person or community.
A little leaven leavens the whole kneaded mass.Your boasting is not good. Do you not know that a little leaven leavens the whole lump?In the meantime, while a countless crowd gathered, so close that they trod on one another, he began to say to his disciples first of all, Watch yourselves from the leaven of the separated ones, which is the mask.THE THREAD
In the meantime, while a countless crowd gathered, so close that they trod on one another, he began to say to his disciples first of all, Watch yourselves from the leaven of the separated ones, which is the mask.Luke uses the same Greek word for leaven and names the Pharisees’ leaven as hypocrisy. That connection sharpens this verse: teaching can spread through a person or community while outward appearance conceals what is working within.
