פֶּחָ֣ם לְ֭גֶחָלִים וְעֵצִ֣ים לְאֵ֑שׁ וְאִ֥ישׁ מדונים [מִ֝דְיָנִ֗ים] לְחַרְחַר־רִֽיב׃ (פ)
As coals are to burning coals, and wood to fire; So is a contentious man to kindle strife.
Mishnah Oktzin
When do honeycombs become susceptible to uncleanness on account of their being regarded as liquids? Bet Shammai says: from the moment he begins to smoke the bees out. But Bet Hillel says: once he breaks up the honeycomb.
