Kedushah
A wonderous story happened with the daughter of the Nesivos. The Nesivos (Reb Yaakov Lorberbaum) zt'l was the rav of Lisa, one of the primary poskim, and wrote the Nesivos HaMishpat on Choshen Mishpat, Chavas Daas on Yoreh Deiah, and other sefarim. This story occurred with his daughter, an almanah, who was traveling with her daughter, a kallah, to buy clothes and other items for her chasunah. They hired a wagon driver to bring them to Lisa, where they would make their purchases.
The problem was that the wagon driver understood that they were traveling with a lot of money to make all their purchases, so when they arrived in Lisa, he brought them to his house, called a friend, bound them, and took away their money.
The goyim heated the oven, getting it ready to burn them. In the meantime, the money was on a table, and they were debating how to divide it.
Suddenly, a German soldier came in. The wagon driver and his friend fled from the house. The soldier untied the women, returned the money to them, and walked with them until they came to an achsanya (inn) where they were able to stay.
That night, the Nesivos (who was no longer alive) appeared to his daughter in a dream and said, "When I heard what was happening to you, I went up to a high place in heaven to daven for you, but my requests weren’t accepted because you had transgressed the prohibition of yichud (traveling with a goy). I went up to a higher place, and I requested that you be saved in the merit of the sefarim I wrote, which increased Torah in Yisrael. This time, my tefillos were accepted, and you were saved. But from now on, you must be cautious with the issur of yichud."
The daughter of the Nesivos told this dream to the people of Lisa, and they wrote it in the city ledger (pinkus). The story was repeated by the Rav of Aliska zt'l, who saw the ledger. (Lev Eliyahu, p.284).
In this story, the issur yichud was an issur d'Rabbanan, because two women are forbidden according to the Rabbanim to be alone with a goy. In our times, Reb Wosner zt'l revealed that being alone with the internet is also forbidden according to halachah. It is a type of yichud. In this story, the almanah and the kallah were about to be burned, and the Nesivos's tefillos, at first, weren't answered because they transgressed the issur of yichud. Let this be a reminder of how careful we have to be with all types of yichud, including the yichud of being alone with the internet.
It states (Zecharyah 2:9) חוֹמַת 'ה נְאֻם ּלָּה אֶה ְיֶה וַאֲנִי סָבִיב ׁאֵש, "I will be for it – says Hashem – a wall of fire around..."
The Imrei Emes zt'l asks that 'ה נְאֻם, "says Hashem," should be written either at the beginning or the end of the pasuk. Why is it placed in the middle?
He answered that the pasuk is saying that Hashem's words should be סָבִיב ׁאֵש חוֹמַת, like a wall of fire, where you can't turn right or left. A decree that must be kept, under all circumstances.
