At the end of the Parsha, we find two known Parshiyot (paragraphs) that are two of the four Parshiyot we place in the Tefillin (phylacteries) that we wear every day.

The obvious question is - what's so special about these Parshyot, that they deserve to be put in our Tefillin?

But more than that, looking in the Psukim themselves, we see something very confusing.

Hashem commands Moshe to tell Am Yisrael about the Mitzvah of Sanctifying all the firstborns, however, Moshe then proceeds to tell Am Yisrael about the Mitzvah of celebrating Pesach for seven days and not eating Chumetz, and only after that, in the next Parshiya, does he tell them about sanctifying the firstborn.

What's all this about? Why does Moshe change from what Hashem said? And what's so special about these Parshyot?
