R. (Shlomo) Zalmen Hena  (רז"ה )  was one of the 

greatest Balei Dikduk. The Pri Megadim calls him 

“Harav Hamedakdek  Hagadol” (O. Ch. 56)

It is said that the Vilna Gaon acquired his knowledge 

in dikduk from the seforim of the Rezah.

In the year 1725 the Rezah printed his Siddur “Bais Tefilah” 

with his pirush “Sha’areiTefillah” . The Siddur has a Haskamah 

from the Chacham Zvi and other Gedolim.

Wherever  the dikduk was incorrect, he corrected and changed 

 the nusach. 

He also changed from leshon Chachamim (KLUM) 

to leshon Torah  (DOVOR) .

Most of the changes in the Bal Hatanya’s Siddur are based 

on the Rezah’s  Siddur “Bais Hatefilah” .

The Rezah was probably one of the first to tamper with  
Nusach Hatefilah. He held that Dikduk overrides the Nusach 
established by the Anshei Knesses Hagedola.
The Yavetz (R. Yakov Emden ) criticized him strongly. He published 
a Sefer (Luach Eres) to point out all the mistakes the Rezah made . 
The Yavetz in his Hakdama writes “It is unbelievable what he(Rezah) 
did. He destroyed and broke fences, moved into territory that doesn’t 
belong to him and there he destroyed and built without permission.

He made changes whenever he felt like it. He had the Haozoh (Chutzpa) 

to tamper with the nusach of the Anshei Knesses Hagedola”.

The Yavetz also claimed that the Haskama from the Chacham Zvi was 
forged,to make a great name for himself .
R. Dovid Yitzchaki claims the other Haskamos were also forged.

R. Mordechai Duseldorff wrote a Kunteres (Kunteres Hahasogos) with 

192 proofs against the Rezah.  The Kunteres has a Haskama from the 

Noda B’yehuda .

It was none other but the Rezah who changed the Nusach of Birchas
Hailonos from “Shelo Chisar Bolomo KLUM to DOVOR (Loshon Torah)

 The Shu”t  Minchas Yitzchok (10 – 16) criticizes the  Siddurim  printers for

changing the Nusach from Klum to Dovor.
