Referencing that previously-cited story of Haman selling himself as a slave to Mordechai, Rashi writes that Mordechai regularly showed Haman his deed of sale written on his shoe. This is why Haman mentions “every time.”
The Me’am Loez notes that Haman does not mention that Mordechai is not bowing down to him. He explains that Haman neglects to mention this because he felt it is beneath him.
The Ben Ish Chai is of the opinion that Haman’s deed of sale was tattooed on Haman’s knee. As class participant RS pointed out, decorating Haman with such a tattoo makes sense because he cannot remove such a sign, and therefore cannot deny it later.
- The Ben Ish Chai continues that Haman knew through numerology that Mordechai would be his chief obstacle in attaining power. This is because their gematrios are similar. How can Haman (5+40+50=95) be similar to Mordechai (40+200+4+20+10=274)? Rather, the gematria of the phrase arrur Haman (“cursed is Haman”) (1+200+6+200+5+40+50=502) is equal to that of baruch Mordechai (“blessed is Mordechai”) (2+200+6+20+40+200+4+20+10=502).
