I Listen to a Rabbi named Rabbi Shaked Bohdana / הרב שקד בוהדנה.
Everything is accounted for in life. What goes around comes around is a Jewish concept. It is called Midah Keneged Midah / measure for measure. You are kind – the kindness comes back.
There is reward and punishment. There is a second chance. G-d allows us to do teshuva (repent).
Rabbi Bohdana says that the Ariz”l says that Mordechai was the Gilgul / reincarnation of Yaakov Avinu. Haman was the Gilgul of Esav – Yaakov’s Brother.
Yaakov erred in bowing to Esav. He bowed to Esav 7 times. His 4 wives followed his action and bowed to Esav. Each of the 11 sons of Yaakov also bowed. Yaakov caused 22 bowings to Esav. In the story of Purim Mordechai – refused to bow to Haman. He repaired the error he made. We read the word “BeOmram” as “KeOmram”. One is written with Bet. The other with a Kaf. The values of each are 2 and 20 respectively. Added together is 22.
Yaakov bought the Birthright from Esav. Esav had animosity because of this. Mordechai bought Haman as a slave. Haman had animosity because of this.
It uses the word “VaYibez” when Esav denigrated the Birthright in Bereshit / Genesis.
It uses the word “VaYibez” when Haman denigrated that it would not be proper to destroy Mordechai – because it would look like a personal vendetta.
Another Parallel is – the 10 sons of Haman are hung. In the Megillah Esther asks the King to Hang the sons of Haman again Tomorrow. When it says “The King” in the Megillah – it also refers to Hashem. She asked Hashem to kill the sons of Haman / Amalek again.
In the Megillah – the Book of Esther (9:6-10), where the 10 sons of evil Haman are killed, three Hebrew letters are written smaller than the rest. These letters [Taf (400), Shin (300), Zayin (7)] when added to 5000 (Hay”), add up to 5707. This is the Hebrew year (1946-1947 C.E.) when 10 Nazi war criminals were hung in Nuremberg, Germany (October 16, 1946) for their atrocious crimes against humanity.
