Every newspaper of the world [!] had reviewed it. Thanks and acknowledgements came, such as from the Bundeskanzler seifel of Austria, Stefan Zweig and many other personalities. In the year 1932 his second work was published with the title "Es verde likht," with a more powerful impression. The reprint was sold out.

In the address book of the German writer was his name, with "the Jewish religious philosopher-writer and biblical scholar."
