R. JUDAH SAID: WE SEARCH [FOR LEAVEN] ON THE EVENING OF THE FOURTEENTH, AND IN THE MORNING OF THE FOURTEENTH, AND AT THE TIME OF REMOVAL.
BUT THE SAGES MAINTAIN: IF HE DID NOT SEARCH IN THE EVENING OF THE FOURTEENTH, HE MUST SEARCH ON THE FOURTEENTH; IF HE DID NOT SEARCH IN [THE MORNING OF] THE FOURTEENTH, HE MUST SEARCH AT THE APPOINTED TIME; IF HE DID NOT SEARCH AT THE APPOINTED TIME, HE MUST SEARCH AFTER THE APPOINTED TIME.
Now this is not the first time that Rabbi Judah and the Sages disagree. And, in fact, the page contains a lot of back and forth accusing Rabbi Judah and the Rabbis of inconsistency in their respective rulings over a broad range of subjects. It feels a little like someone who has been holding on to resentments and finally let them all out!
But, there is a really interesting example given in the next Mishnah of who the times for searching for leaven were announced:
R. JUDAH SAID FURTHER: TWO UNFIT LOAVES OF THE THANKSOFFERING USED TO LIE ON THE ROOF OF THE [TEMPLE] IZTABA (Portico):
AS LONG AS THEY LAY [THERE] ALL THE PEOPLE WOULD EAT [LEAVEN];
WHEN ONE WAS REMOVED, THEY WOULD KEEP IT IN SUSPENSE, NEITHER EATING NOR BURNING [IT];
WHEN BOTH WERE REMOVED, ALL THE PEOPLE COMMENCED BURNING [THEIR LEAVEN].
