Our parasha ends with a list of the offspring of Avraham’s brother, Nachor, most important among them being Rivka, the daughter of his son, Betuel. While most of the children (eight) were from his wife, Milka, he also had four children from his concubine, Reuma (see Bereishit 22:23-24). Thus, there were twelve children, which certainly reminds us of the twelve tribes that were born to Yaakov from his wives (8) and servants (4). While some say that the reason for all this genealogy is to understand where Rivka came from (see Rashi ad loc.), we will try to figure out who the last person mentioned in the list, Ma’acha, was, and what Ma’acha’s connection to Bnei Yisrael was over time.
