“As your sword has bereaved women,
So shall your mother be bereaved among women.”
And Samuel cut Agag down-b before the LORD at Gilgal. (34) Samuel then departed for Ramah, and Saul went up to his home at Gibeah of Saul.
Remember what etc you were famished and weary, and cut down all the stragglers in your rear: he did not fear God. (Deut. 25:17-18) It seems, that it is not only for this that the seed of Israel is being commanded regarding the erasing of Amalek, which is from the seed of Esav. Rather, every person in Israel needs to erase the evil part that is concealed in one's heart, that is known by the name Amalek. This is because whenever the seed of Amalek is found in the world it is found in the human being, since the human is a small world, and therefore there is a reality to "Amalek", to the force of evil inside every human being, which arises every time to make a human being sin, and is regarding this that the remembrance comes in the Torah. And behold, the strength of the seed of Israel is only found in the mouth, since "the voice, is the voice of Yaakov", [found] in the Torah [study] and in prayer, when a person has this force always burning within towards the Holy One of Blessing, then no evil can control him. But, when a person allows this force to rest then immediately [s/he is under the verse] "and they left Refidim" meaning "their hands became weak [rafah]" and instantly "and Amalek came", instantly evil takes over. But when a person seizes in any instance the character trait of "awe", meaning, one is in awe of the Holy One of Blessing and will not transgress God's commandments, in any instance he won't come to sin. And this is why "you were famished and weary" is written, that you did not have inside you the force of the seed of Israel, that their hands were weakened and did not serve God. "And did not fear God" - and from this you need to remember strongly, so that the force of Amalek will not make you stumble. And this is why it is written "And it was, when Moses raised his hand" (Exodus 17:11) this means the force that is known by the name "hand" - when a person raises that force, then "and Israel prevailed." But when he allowed that force to rest, then - God forbid - "and [the other side] prevailed, etc.
The Gemara adds that some of Haman’s descendants studied Torah in Bnei Brak, and some of Sisera’s descendants taught children Torah in Jerusalem, and some of Sennacherib’s descendants taught Torah in public. Who are they? They are Shemaya and Avtalyon, the teachers of Hillel the Elder.
