Join Meir Panim’s campaign to “light up” Chanukah for families in need.
With these principles in mind, what can we kasher in the kitchen? Plastic and nylon materials are the subjects of halachic debate. According to Rav Moshe Feinstein, synthetic materials made of chemical mixtures such as plastic and nylon cannot be kashered for Pesach. According to other opinions, plastic or nylon vessels may be kashered. This can be done either by the process of hagalah or, if this will damage the vessel, by the dual process of immersing it in hot water that has been removed from the fire and then by the procedure of milui veirui. According to Rav Moshe, Pyrex, Duralex and Corningware cannot be kashered. Others permit the kashering of Pyrex and other heat-resistant glass utensils by the process of hagalah if used for hot food and by the process of milui veirui if used for cold food. According to Rav Moshe, dishwashers lined with plastic walls cannot be kashered.
According to other opinions, a plastic-lined dishwasher can be kashered in the following way: First, it must be thoroughly scrubbed. Then it should not be used for twenty-four hours. Then the dishwasher should be turned on to allow boiling water to spray inside. Dishwashers lined with porcelain or enamel cannot be kashered. Gas or electric ovens can be kashered by libun and according to some poskim even by libun kal. According to Rav Moshe, such ovens can be kashered by running them through the self-cleaning cycle.
Microwave ovens can be kashered. They should be thoroughly cleaned and not used for twenty-four hours. Then a bowl of water should be placed inside. The microwave oven should then be turned on until the inside is filled with steam.
Mixers used for mixing dough or other chametz can generally not be kashered because it is almost impossible to remove the chametz particles trapped in the machine. Blenders that can be dismantled should be thoroughly cleaned and their metal parts and bowls immersed in boiling water. Coffee percolators, to the extent that they can be thoroughly cleaned of all chametz particles, can be kashered by boiling water inside them. Rabbi Shimon Eider, however, writes that they should not be kashered because it is impossible to clean out all chametz particles.
According to most opinions, whisky glasses cannot be kashered because they retain the smell and flavor of whisky. The Aruch Hashulchan (Orach Chaim 451:49), however, rules that they can be kashered by milui and irui.
Because there are so many conflicting opinions in this area of halacha, in case of doubt a rabbi should be consulted.

Rabbi Yaakov Nagen, a Ram at Yeshivat Otniel, notes that the verse is suggesting that retelling the story of the Exodus is so important that Hashem is performing ever-greater miracles specifically so that parents can tell their stories to future generations.
Before performing the 10th plague God makes a fundamental argument about the ultimate nature of justice.
How is it possible that the clothing was more valuable to them than gold or silver?
Question: If Abraham was commanded to circumcise his descendants on the eighth day, why do Arabs – who claim to descend from Abraham through Yishmael – wait until their children are 13 to circumcise them? I am aware that this is a matter of little consequence to our people. Nevertheless, this inconsistency is one that piques my curiosity.
“It means that the disqualification of relatives as witnesses is a procedural issue, not a question of honesty,” explained Rabbi Dayan.

Although the conversion ceremony involves more than circumcision and immersion, these are the two essential requirements, without which the conversion is ineffective.
If a man dies childless, the Torah commands the deceased’s brother to marry his brother’s widow in a ceremony known as yibum, or to perform a special form of divorce ceremony with her known as chalitzah.
What if, at the moment of the late brother’s death, the surviving brother cannot effect yibum because the widow is a niddah?
