Why did Rav Yosef ben Chama stop taking his debtor’s Avadam and using them for work?
It was a problem of Gezel.
It looks like Ribis.
They were lazy and didn’t get the job done.
This weakened them, and they couldn’t work as efficiently later on.
It prevented them from working for their masters during this time.
The Malveh used the Loveh’s property worth ten for a Ribis payment of twelve. How much must he repay the Loveh?
Ten, because this is the amount of money he saved, i.e. benefitted through Ribis.
Really ten, but he must pay twelve as a Knass, to deter him from taking Ribis in the future.
Twelve; he realized that he was paying twelve for a service for which other people would pay ten, and he accepted it.
He must pay ten but, if the Loveh is Tofais twelve, we cannot take it away from him.
Eleven, as a compromise.
When is rent essentially due, and when is payment for a sale essentially due?
Both are essentially due only later, after a period of time.
Both are due immediately.
Rent is due immediately, and payment for a sale is essentially due only at the end of the installment plan.
Rent is essentially only due at the end of the rental period, and a payment sale is due immediately.
Rent is only due at the end of the rental period when the landlord is being paid for something else up front.
When may both the buyer and seller eat Pairos from the property?
When the seller says, “Be Koneh now according to the amount which you paid.”
When the seller says, “When you pay the rest of the money, you can eat from now.”
When the seller says, “When you pay the rest of the money, you may be Koneh the entire property.”
When the seller says, “Be Koneh from now, and the remaining money should be a loan that you owe me.”
Never.
Which rulings aren’t like R. Yehuda?
Neither the buyer nor seller may eat Pairos if the seller says, “When you pay the rest of the money, you can eat from now.”
A lender may not tell someone whose property he is holding as collateral for a loan, “If you decide to sell it, sell it only to me, for a beneath-market price.”
A person may not sell a property on condition that he may buy it back when he gets the money.
