Harav Chaim Yitzchak Eizik Yustman
Harav Chaim Yitzchak Eizik Yustman was born his father, Rav Yaakov Aryeh in 5593. He learned most of his Torah under the Chiddushie Hari’m, and was one of his prime talmidim.
Harav Yustman taught many talmidim through his life, and he became known throughout Poland as a gaon who was proficient on Toras Hanigleh and Nistar. He wrote chiddushim on Shas, on Torah and on the Zohar, some of which were printed in his sefer Chayei Yitzchak al haTorah and in sefer Siach Yitzchak on Shas.
In his introduction to Chayei Yitzchak he promised: ‘‘Anyone who will take on the task and print a compilation, or who will be supportive and assistive, or will purchase my compilations, I will advocate for him and be there in a time of pain or illness, R’’l may it not come, and at every opportunity that I can.’’
He passed away on 3 Nissan 5671 and was laid to rest in the Gensha Cemetery in Warsaw.
Rivka Answered Amen After Yitzchak’s Brachah
After Yaakov was blessed by his father, Yitzchak, it says (Bereishis 27:30): ‘‘Vayehi ach yatzo yatza Yaakov me’eis pnei Yitzchak.’’ The redundant words ՅԱԱ ՅԱԱ come to teach us that when Yitzchak blessed Yaakov, Rivka answered amen to his brachos, as amen is numerically equivalent to Ա’’Յ. The reason that the Torah said ՅԱԱ ՅԱԱ twice is to teach us that Rivka answered amen to each one of the two pesukim of the brachos of Yaakov, the same way we answer amen after each one of the three pesukim of Birchas Kohanim. Therefore, even after Yitzchak discovered his mistake, he said about Yaakov (passuk 33) ‘‘gam baruch yihiyeh’’ – because he knew that a brachah that is answered by amen will be fulfilled.
For this reason, even when Rivka quoted to Yaakov what Yitzchak told Eisav, she said (Bereishis 27:6-7): ‘‘I have heard your father speaking to Eisav your brother, saying, bring me game and make me tasty foods, and I will eat, and I will bless you before the Hashem before my death.’’ Rivka added the words ‘‘lifnei Hashem’’, which Yitzchak didn’t say, because she knew that when she would answer amen to his brachah, the brachach would be considered to be ‘‘lifnei Hashem,’’ as it is known that amen is numerically equivalent to the Names of Havay-ah and Adnus.
