3.07 Vayero 5783

1) In Eretz Yisroel it is prevalent that at [the daily] Birchas Kohanim, the Chazan, when prompting the Kohanim word for word, does so in an undertone. Whereas elsewhere, the Chazan says his part in a regular tone. What’s the Chabadtake on this? 2) A question from Ukraine:  We are suffering frequent power cuts. Our communal kitchen is manned by non-Jewish staff. In order to address the issue of Bishul Akum, I normally switch on the electrical ovens at the beginning of the day. Now, when power is restored, is it necessary for me relight the ovens? 3) In our nursery, we made Challos. For some reason, a non-Jewish helper placed the Challos in the oven. What is the status of the Challos and that of the baking tins? 4) A Jewish man is living with a non-Jewish woman. He is keen to put up a Mezuza, and she is equally keen. Does it make any difference – re. saying a brocho - if the house is her property? 5) When affixing a Mezuza to the door of a shop, is a brocho said? 6) In error, I said the brocho Mezonosover bread that is actually Hamoitzee; do I now need to say the correct brocho? 7) What if I only realized my mix-up after having recited Al haMichya; do I now need to recite the full bentshing? בס' שבת כה בנדו"ד. ראה יו"ד מד. בשו"ע יו"ד סי' קיב ש"ך סק"א משמע דלא מהני עריכת ישראל. וכן מפורש בערוך השלחן שם סעיף י. הערה בקי. ראה אגרות. שליחות כ 96. שליחות כ 96.
