Esther 4:14, Question 2. Why does the verse use the word “revach” in reference to the Jews’ security?

In Bireishis (32:17), in the momentous meeting between Yaakov and Eisav, Yaakov tells the messengers with whom he famously sent gifts to place a “revach” (“space, comfort”) between each other. Baal HaTurim points out there that this word is used only twice in all of TaNaCh – there, and in our verse. He writes that this is a hint to the idea that Jews would need to resort to bribery in many societies to receive fairness in judgment. Esther’s succumbing to Achashverosh would be the act which would lead to the Jews’ salvation.
