The opening as it read in 2025
Zera Yisrael ( Hebrew : זרע ישראל , lit. ' Seed [of] Israel ' ), also known as Zera Kadosh ( lit. ' Seed [of] Holiness ' ), is a legal category in Halakha that denotes the blood descendants of Jews who, for one reason or another, are not legally Jewish according to religious criteria. This is usually due to a lack of matrilineal Jewish ancestry.
