Iscah (Hebrew: יִסְכָּה – Yiskāh; Greek: Ιεσχά) is the daughter of Haran and the niece of Abraham in the Book of Genesis. The passage in which Iscah is mentioned is extremely brief. As a result rabbinical scholars have developed theories to explain it, typically adopting the claim that Iscah was an alternate name for Sarah (Sarai), the wife of Abraham, particularly that it denoted her role as a prophetess.
