The final chapter of Tractate Nazir opens on today’s daf with a mishnah that teaches this: Non-Jews do not have nazariteship. The Gemara will inquire about the source of this rule, citing the fact that the chapter of the Book of Numbers outlining the laws of naziriteship opens with the phrase: “Speak to the children […]

Can a person accomplish two goals with one act? That is the question raised on today’s daf by the students of Rabbi Shimon ben Yohai.  A pure nazir and a leper, what is the halakhah? May he shave one shaving and it will count for him for this and for that? Both a nazir at the end of […]

This multinational lab study was conducted in collaboration with Sheba Medical Center at […]

Gestational diabetes – a potentially dangerous condition for the mother and fetus – can be diagnosed as early as the first trimester of pregnancy, months earlier than typically detected, according to a new study at Bar-Ilan University (BIU) in Ramat Gan. GDM (gestational diabetes mellitus) is a condition in which women without diabetes develop glucose […]

Haroset (AKA charoset or halek/halaq) is a staple Passover spread or paste made with a mixture of fruit, nuts, honey, wine and spices, to symbolize the mortar that was used by Jewish slaves to make bricks in Egypt. While haroset is typically only seen on the Passover seder plate, I’ve used the flavors of my […]

Although the benefits of exercise are well-documented in millions of studies, one workout has a really negative downside.  Dr. Gerald Imber, a New York-based plastic surgeon who frequently shares anti-aging tips and advice on TikTok, addressed the issue in a recent video. He said that running long distances can lead to a skinny and old […]

After multidisciplinary and life-saving treatment […]
