Chasidut zu Bereschit 35:21

Migdal Eder: A place in Israel, mentioned in Gen. 35:21. It seems from Scripture that it is the vicinity of Bethlehem. Our forefather Jacob camped in the environs of Migdal Eder after he lost his wife Rachel, who was buried in Bethlehem. According to the translation of the second-century sage Yonasan ben Uziel, Migdal Eder is the place of the Messiah, as well as his name.
