At the end of Parshas Va'eschanan all the Chumashim I have seen (example 1) (example 2) (example 3) mention that there are 118 verses - Uziel Siman - as Uziel = 118. Artscroll Chumash has the same information. Yet if one counts the verses, there are actually 122. What is the reason for this discrepancy?
Those Chumashim are unfortunately mistaken. All old manuscripts of the Torah have listed that there are 119 verses (see clips from 8 of them here). If you count the Decalogue as 10 verses, as is read in Taam Elyon, then you get 119. Problem solved.
the same thing happens in parshas yisro 72 and 75- I was told that the 10 commandments can be grouped slightly differently than originally eg lo signov lo tirzoch were possibly previously in one verse other discrepancies in parshas Bo and Vayishlach - I don't have an answer for that :(
