Iscah [SEP] present in work
Iscah
Iscah ( – "Yiskāh"; ) 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.
The Babylonian Talmud connects the name Iscah to an Aramaic verbal rooting meaning "to see", connecting
; and the name of Nahor's wife, Milcah, the daughter of Haran, the father of Milcah, and the father of Iscah.

Rabbinical interpretation.
Since Haran is described as the father of both Iscah and Milcah, Rabbinical scholars concluded that Iscah was another name or title for Sarai. This was formulated in the Targum Pseudo-Yonathan. Howard Schwartz explains:
Rabbi Isaac commented "Iscah was Sarah, and why was she called Iscah? Because she foresaw the future by divine inspiration.
