His mother obtained falsified birth certificates with incorrect dates for her sons, marking them as three years younger than their actual ages so they would not be enrolled in state-supervised schools under the Yevsektsiya.

[7] In the month of Nisan 1934, their father managed to secure a permit to emigrate to the Land of Israel, assisted by Rabbi Kook, and requested his sons return to Shumyatch.

Since there was no religious school in Ramat HaSharon, their father taught the boys at home, using crates of oranges as desks due to a lack of furniture.

[7] A year later, their father remarried to Rachel, and he asked his sons to return, explaining that with the rebbetzin now taking on household responsibilities, they could focus on their studies without interruption.

The founder of the yeshiva, Rabbi Yosef Shlomo Kahaneman, appointed him to teach Holocaust survivor students who had arrived at the orphanage institution "Batei Avot."

However, as he was already holding a position at the yeshiva and due to his wife's refusal to relocate from Bnei Brak, the role was assigned to his brother, Rabbi Yaakov Edelstein.

Following this, a rally of support was held at his yeshiva, attended by Rabbis Chaim Kanievsky, Michel Yehuda Lefkowitz and Nissim Karelitz.

[15] In May 2023, during the holiday of Shavuot, Rabbi Edelstein was admitted to Mayanei Hayeshua Medical Center in Bnei Brak due to breathing difficulties.

According to him, when the style of learning aligns with the learner’s character, their enjoyment and satisfaction increase, making it easier to persevere in study over the years, in line with the Litvak ideal.

Additionally, he considered acquiring familiarity and expanding knowledge essential for forming sound logic and a proper understanding of Talmudic discussions, providing greater satisfaction for the learner.

In most of his talks, he encouraged the importance of mussar study, even mentioning its necessity in the eulogy he gave for Rabbi Chaim Kanievsky, noting the benefits it brings to a person’s character and all areas of life.

Rabbi Edelstein encouraged educators to form personal connections with their students, which he considered the foundation for instilling a love of Torah in children.

In a talk to married yeshiva students (avreichim), he said: Sometimes people behave unnaturally due to various calculations and mistakes, such as someone immersed in their studies who avoids trivial conversation, to the extent that they overlook proper consideration for their family and those around them.

[22]He viewed those who left religious observance (yotzim beshe'ela) and "dropouts" as "tinokot she'nishbu" (literally, "captured infants"), calling for them to be "treated with honor and friendliness."

He advised providing them with financial support, even for needs like clothing that might not align with religious standards,[23] alongside an effort to inspire change through gentle persuasion.

[24] He advised men struggling with shalom bayit (marital harmony) to follow what he called "silence and respect," meaning: the husband should remain silent when his wife expresses dissatisfaction or anger toward him, and should not respond so as to avoid escalating a conflict.

[25] He frequently emphasized in his weekly talks that even if one spouse is angry with the other, they must not raise their voice, as self-restraint prevents anger both in marital relationships and interactions with others.

If a secular Jew is willing to risk his life more than a Haredi, he is greater than him.”[27]The statement sparked controversy and led to delegations pressing him to retract it, but he refused.

[29][30][31] Rabbi Edelstein opposed the current operations of the Rabbinical Committee for Communications, due to claims that it was blocking necessary content for the Haredi public without consulting its leaders.

[32] Rabbi Edelstein believed that the prophecy of redemption in Ezekiel Chapter 36 was being fulfilled in his days, asserting that God was keeping the promise of Ingathering of the Exiles to sanctify his name and was rebuilding the Land of Israel.

He explained, based on the prophet's words, that redemption begins for the sake of sanctifying God's name even before Am Yisrael (the people of Israel) has fully repented.

His brother-in-law, Rabbi Reuven Yosef Gershonowitz (married to his sister Pesia), served as the head of the Hemdat Shmuel Yeshiva in Hemed and Yeshivat HaNegev in Netivot.

Another brother-in-law, Rabbi Yitzhak David Breitstein (married to his half-sister Shoshana Rivka), served as the safra d'dayanei (scribe to the judges) in the Badatz (Haredi court) of the Edah HaChareidis in Jerusalem.
