The opening as it read in 2025
Jewish ritual period A vach nacht ( Yiddish : וואך-נאכט , lit. ' watch night ' ; also vacht nacht or vakhnakht ) or Brit Yitzchak ( Hebrew : ברית יצחק , lit. ' covenant of Isaac ' ) is the night before the brit milah of a male Jewish child, when he is in need of added spiritual protection. A standard "vach nacht" custom, practised by many Ashkenazi Jews , is to have children come and recite the Shema Yisrael and other verses from the Torah near the baby.
