תמחה את זכר עמלק THOU SHALT WIPE AWAY THE REMEMBRANCE OF AMALEK, — both man and woman, infant and suckling, ox and sheep (a quotation from I Samuel 15:3, stating how the Amalekites were to be destroyed), so that the name of Amalek should never again be mentioned even in connection with a beast, in that one could say: “This beast belonged to Amalek” (Pesikta Zutrata).
זה אלי THIS IS MY GOD — In His glory did He reveal Himself to them and they pointed to Him — as it were — with the finger exclaiming “This is my God!” (Shir HaShirim Rabbah 3:15) A maid servant beheld at the Red Sea what even the prophets never saw (Mekhilta d'Rabbi Yishmael 15:2:2).

He replied: The verse states after Adam ate from the tree of knowledge: “Have you eaten of [hamin] the tree, about which I commanded you that you should not eat?” (Genesis 3:11). Hamin is spelled in the same manner as Haman: Heh, mem, nun.
