In this week's parsha, we see a parsha (stumah) "break" in the middle of Devarim 2:8.
There are several other places where there is a parsha break in the middle of the verse. Another example occurs in Bamidbar 26:1. Aseret Hadibrot (10 commandments) also has this. I am not referring to Az Yashir or Ha'azinu as these are written in a special style, and are not considered "parshi'ot" according to the usual rules.
Is there a general reason why there is a parsha break in the middle of a verse, or does each verse have its own unique reason? If it's the 2nd reason, can you explain why there is a break in Devarim 2:8?
