Torah portions that end abruptly?

Question

In parshat Va-era the 2nd portion - Sheini ends rather abruptly (in the middle of a sentence) Shemot 6:28:

Now it came to pass on the day that the Lord spoke to Moses in the land of Egypt, <-- [Sheini ends here]

Rashi also notes:

[This is] connected with the following verse: [“That the Lord spoke to Moses”].

Is there a special reason here why Sheini ends so abruptly....

or are there many cases where this happens -

(which would possibly mean that the separation of the portions does not necessarily denote the 'end' of a topic and the start of a new one)

Answer 1

The Ibn Ezra says he is surprised at why there is a new paragraph here. He doesn't answer his question, but he says the one who divided the sections must have had a good reason, because he is much smarter than we are.

Answer 2

The Kli Yakar says that it is to emphasize that the verse stands alone - it is telling us that Hashem spoke to Moshe by day, and not at night, unlike all the other prophets.
