Reference for Megillah 20:20

תחת הנעצוץ תחת המן הרשע שעשה עצמו ע"ז דכתיב (ישעיהו ז, יט) ובכל הנעצוצים ובכל הנהלולים

“Instead of the thorn”: instead of the wicked Haman who put himself up as an object of worship, as it is written, “And upon all thorns and upon all brambles” (Isaiah 7:19) “shall come up the cypress”: this is Mordecai who was called the chief of all spices, as it is said, “And you shall take for yourself the chief spices, flowing myrrh (mor)” (Exodus 30:23), which we translate [in Aramaic],
