Talking Talmud Yardaena Osband & Anne Gordon

Consecrated items for which one bears responsibility are subject to price fraud, but when one is not responsible, price fraud is irrelevant. But what does it mean for the consecrated property to belong to God? What about the human dimension? Plus, taking advantage of market demands, for better and worse. Also, a new mishnah - on "ona'at devarim" -- oppression or exploitation or just plain obnoxious speech.

When is the capacity to take advantage of another not relevant? And if there's no risk of exploitation, is there any recourse to cancel the transaction for other reasons? Note the exceptions of consecrated property (hekdesh) and land... Also, what if transactions or loans are made in conjunction with consecrated property? The Temple has some flexibility with fluctuations in the costs of things - without it being exploitative.

A Mishnah lists cases where onaah does not apply and the Gemara discusses the scriptural sources for these categories.

2 mishnayot - Mishnah 1: Determining the differential to be considered exploitative, the amount to swear, and the amount to admit to owing money. Plus, 5 cases that depend on the equivalent of one perutah. Also, Mishnah 2: 5 halakhic categories for which "one-fifth" is relavant as an element of the halakhah.

The daf discusses a variety if different aspects about the chomesh.

The daf discusses what to do if one’s maaser sheini produce is worth less thana perutah and need to deconsecrate it onto coins.
