Luke 12:1
In the meantime, when a crowd of many thousands had gathered, so that they were trampling on one another, Jesus began to speak first to his disciples: Beware of the yeast of the Pharisees, which is hypocrisy — the warning repeats 11:39 in a new key, shifting from exposé to protective instruction. The disciples who have just heard Jesus demolish the Pharisees' external piety are now warned against the same internal corruption taking root in themselves.
