Esther 1:21, Question 3. Why does the verse say that Achashverosh acted “according to the word of Memuchan” instead of the more standard, “and the King did so?”

Rav Yaakov Lorberbaum of Lissa writes in his Megillas Sesarim that Achashverosh followed Memuchan’s advice in detail; he did not change a single word. Perhaps Memuchan’s use of the phrase “that he made” about Achashverosh’s decree in the previous verse indicates that he slyly convinced the king to think the decree was something he, himself, made; he made him think he came up with the idea. So it is no wonder the egomaniac followed these words to the letter!
