And you shall eat before Hashem your God, in the place that He will choose to make His Name dwell there, the tithe of your grain, of your wine and of your oil, and the firstborn of your herd and of your flock, in order that you may learn to fear Hashem your God all the days.
English: "Your wine" — Rav Kahana posed a contradiction: it is written "tirosh" yet we read "tirosh." If one is privileged, it makes him a head; if not, it makes him poor.
On the daf / in context: The dual spelling/reading of the word for wine is taken as an allusion to the two possible effects of wine: wisdom or poverty, depending on how it is used.
Type of Learning
Derash on the verse (Yoma) — wine can elevate or impoverish.
What Is Learned
Wine, when used properly, makes one a "head"; when abused, it makes one poor.
