Abumazen
Encouraged by the close meeting between Abu Mazen and Amalek, Rabbi Glazerson decided to add additional terms. He chose Dog because Amalek is associated with dog, recalling the verse
Remember what Amalek did to you. (Deuteronomy 25:17)
The Zohar asks,
What is the reason? It is similar to a son that breaches a fence and gets bitten by a dog. Every time the father wants to reprove his son, he says to him, Remember when the dog bit you? Here too, "you shall see it and remember," (Zohar Shlach Lecha)
Also Rabbi Glazerson added the term Enemy recalling the verse
God will then direct all these curses against your enemies and against the haters who pursued you.(Deuteronomy 30:7)
Rabbeinu Bachya writes on this verse:
The former are the Ishmaelites, Arabs: the latter refer to the descendants of Esau. (Torah Commentary of Rabbeinu Bachya, Eliyahu Munk, trans., Vol 7, p. 2739.)
The reason why the descendents of Esau are referred to as haters is that God himself refers to them as haters:
I have hated Esau. (Malachi 1:3)
Elaborating on this explanation, Rabbeinu Bachya writes,
The reason the term hater is applied to the Roman Empire whereas the term enemy is applied to the Islamic Empire is that enemy is a term describing a fiercer hatred and animosity than hater. An enemy is one who is full of hatred in his heart and knows no mercy. A hater on the other hand, though he too inflicts hurt and death, tempers it with a degree of mercy. (Torah Commentary of Rabbeinu Bachya, Eliyahu Munk, trans., Vol 7, p. 2741.)
