He was called Yitzchok Zev Myadler, which people misinterpreted as meaning "mi-Yadler," denoting "from Yadler" in Hebrew.

Whenever his father would perform a siyum on completing a Talmudic tractate, young Benzion would deliver an aggadic lecture.

As his fame spread, Yadler began lecturing in other synagogues in Jerusalem and eventually in Jaffa and other settlements throughout Palestine.

He would ride donkeys between the moshavot, from Metula in the north to Be'er Tuvia in the south, in order to instruct the farmers in these mitzvot.

In 1914, he participated in the rabbinical delegation that Rabbi Kook organized to visit the Jewish settlements in the northern part of the country.
