Mamzer

The Hebrew noun mamzer (Hebrew: ממזר‎) in the Hebrew Bible and Jewish law, is a person born from certain forbidden relationships, or the descendant of such a person. A mamzer is someone who is either born of adultery by a married Jewish woman and a Jewish man who is not her husband, or born of incest (as defined by the Bible), or someone who has a mamzer as a parent. The mamzer status is not synonymous with illegitimacy, since it does not include children whose mother was unmarried.
