Parashat Bo begins with the three final plagues that G-d uses to smite Egypt:
These mirror the three last mitzvot of the parsha:
Destruction of food is present in Bi'ur Chametz as well as Makkat Arbeh.
Tefillin, alluded to here, are placed 'between the eyes'- which control sight, and on the arm, which controls movement. Ever notice how Tefillin are a little restrictive? Like, it's hard to shoot a basketball while wearing Tefillin? This mirrors Makkat Choshech, where it was impossible to see, and the darkness was so heavy, it was impossible to move.
Our firstborn are given to G-d because during Makkat Bechorot, Hashem killed their Egyptian counterparts but saved Jewish firstborn.
