Through His Labor in Torah, He Merited That His Waters Should Spread to the Public – A Letter of Endorsement from Rabbi Elazar Menachem Shach zt"l – Bnei Brak 1975
This is a fervent letter of endorsement, full of praise, dated 4th of Iyar, 1975, sent by Rabbi Elazar Menachem Shach, the Rosh Yeshiva of Ponevezh, to Rabbi Yehuda Asher Levenberg, a contributor to the collective Torah study in the city of Torah, Lakewood, regarding his book "Amrei Chen" on the topic of the Passover sacrifice and the laws of sacrificial offerings.
In his words, Rabbi Shach writes that the author’s words "were said with a clear and deep understanding… they are worthy to be disseminated and many will benefit from his book!" He continues, "His labor in Torah has caused his waters to spread to the public." Rabbi Shach signs off with his personal signature and stamp.
