English: Rav Kahana posed a contradiction: It is written “tirash” but we read “tirosh.” If one merits, he becomes a head (rosh); if he does not merit, he becomes poor (rash).
On the daf / in context: The ketiv/keri of the word for wine is taken as a moral lesson about the dual potential of wine: wisdom or poverty, depending on how it is used.
Type of Learning
Custom (Bavli — dual potential of wine: rosh or rash)
What Is Learned
Wine can make a person a “head” (wise and clear) or a “pauper,” according to whether one uses it properly; the dual spelling of tirosh/tirash is the source.
