The seventh aliyah(section) of Parshas Bo includes two of the paragraphs that are inside of tefillin. These paragraphs discuss the sanctity of the firstborn, who were saved even though all of the Egyptian firstborns were killed. We explore the differences in the 2 paragraphs, as well as their significance. As the chosen nation, we have the special status as Hashemâ€™s bechor (firstborn). The first has extra sanctity because it is similar to Hashem, who is the beginning of everything. With these 2 paragraphs in tefillin, we explain to our children who we are, and what our place is in the world.
