DAF HASHAVUA

(Bava Kama 54b-55a) 

R. Chanina ben Agil asked R. Chiya bar

Aba , why in the first Dibros it doesn't say Tov (L'maan Yitav) and in the

last Dibros it does say Tov.

R.Chiya b A. answered, "instead of asking me "why" ask if it does

say Tov or not. I am not familiar with the text of the Aseres Hadibros-".

Tosfos (Bava Basra 113a dh Tarvyhu) proves from this Gemoro

that there were times where the Amoraim weren't familiar with

Pesukim in the Torah. 

The Ibn Ezrah (Shmos 20 :1) enumerates the differences between the

Aseres Hadibros in Parshas Yisro and in Parshas Voeschanan.

One of the differences ho points out is , In Parshas Yisro it says עבדו ואמתו

first and then שורו וחמורו and in Parshas Voeschanan it says שורו וחמורו

first and then עבדו ואמתו  .

The last time I checked, in both  Parshas (Voeschanan ,and Yisro) it says  

first  עבדו ואמתו   and then שורו וחמורו . (no difference)
