Ohalivah, Ohalivamah, Yehudah, and Yehudit
Something interesting I noticed today while reading Rashi on Vayishlach. While discussing the wives of Esav, Rashi noted that the wife called Ohalivamah (אהליבמה) bat Anah ( Beresheet 36:2 ) is the same as Yehudit (יהודית) bat Be'rei ( Beresheet 26:34 ). And that led me to wonder: In the Tanach (e.g. Yechezkel 23:4 ), and in later sources, especially piyyutim lamenting the destruction and exile ( some examples ), Judah is often called "Ohalivah", which is very similar to Ohalivamah, who is supposedly Yehudit (Judith, same root as Judah). It begs the questions: Why would Ohalivah/Judah be called after one of the wives of Esav, and is Ohalah (Israel in the same sources) also named after someone? (image taken from here )
