As noted earlier (three posts ago), the Talmud (Megillah 12b) states that Mordechai’s father was from the tribe of Benyamin. Rav Yitzchak Hutner adds that this is an important detail to the story because, when Haman becomes incensed at Mordechai’s refusal to bow to him (Esther 3:5), the Midrash (Esther Rabbah 7:8) has Haman say, “All the tribes bowed to my ancestor, Eisav (Bireishis 33:3)! Why won’t you bow to me?” Mordechai answers, “All the tribes bowed except for Benyamin, for he was not yet born. Therefore, I need not bow to you.”
Another reason this is important is that Esther is related to Mordechai by being “daughter of his uncle” (Esther 2:7). Therefore, she too comes from the royal house of King Shaul, and may be prized by Achashverosh for this.
“Yimini” could also mean that Mordechai was right-leaning. In Kabbalistic thought, this means he had a focus on “chachmah” – masculine, logical, and linear knowledge – rather than “binah” – feminine, instinctual, global wisdom. With H-Shem’s help, this insight into Mordechai’s character will help us to better understand his argument with Esther (4:11-16) about the best way to combat the coming threat to Jewish survival.
