Lecture - Brunch with Rabbi Bronstein

Aleinu leshabeaj is the declaration of faith that closes all prayers throughout the year. How and why did it go from being an introduction to a section on Rosh Hashanah to being this culmination?

Why in some Siddurim there are 2 verses from Isaiah before the phrase we bow to and in others (our books) this phrase is omitted?

Was it censorship from external power or is it self-censorship? This past January 10 (Tuesday) we had in Atid the conference - Brunch with Rabbi Bronstein, who clarified this and many more doubts.

We appreciate the assistance of all attendees and we hope to meet the Rabbi again soon.
