Can a Lender Charge the Borrower for the Opportunity Costs of a Loan?

July 13th, 2021|Choshen Mishpat|


Washington, D.C.

Rabbi Linzer, one person wants to lend a large sum of money (short term loan) to a someone. The lender will withdraw money from an investment account to do this. In order to liquidate the investments, the lender  will have a tax penalty and also have opportunity costs because he wont be making money over the course of the short term loan. I assume it is ribit to charge for the opportunity costs. Can the borrower pay the capital gains tax […]

Saying The Bedtime Shema If Going to Sleep in The Morning

July 12th, 2021|Berakhot, Orach Chayim, Shema and Shemoneh Esrei|


Midwest, USA

Shalom Rav, I have a congregant who is taking on a night job where he will work all night, arrive home after sunrise and then go to bed. Since his now kavua “bedtime” is in the morning he asked if he could still say the bedtime Shema. The Biur Halakha on Shulchan Arukh OC 239:1 seems to clearly say one should not, at least not the berakhah, and the Arukh HaShulchan mentions that the point of the Shema al HaMitah is to protect from demons, […]

Birkat Eirusin When the Bride or Groom Cannot Drink Wine

June 18th, 2021|Berakhot, Even HaEzer, Kiddushin and Ketubah, Orach Chayim|


South Central, USA

I’m officiating at a wedding, and the kallah said she can’t drink wine or grape juice. The only liquids she can drink are water or tea. What would you recommend they say the berakhot over at the wedding? Thank you.


A couple of possibilities:

1. The chatan can drink without the kallah doing so.

2. You don’t need wine really – Shulchan Arukh EH 62:1 ואם אין יין מצוי מברך על השכר.

3. Bedieved you don’t need a kos at all. See Beit Shmuel there who writes ואם אין […]
