In this week’s Torah portion, one of the things we learn about is how the Children of Israel offered the Passover for the very first time since their departure from Egypt (Numbers 9:1–14). It had been a full year since they left Egypt and it was time to fulfill the instructions they had previously been given: “You shall therefore keep this statute at its appointed time from year to year” (Exodus 13:10). Therefore, Moses instructed the Israelites to offer up the Passover at the appropriate time in the second year:
Our parashah begins with God telling Moshe, “Ani Hashem” (6:2). Isn’t this obvious? Hasn’t He already revealed this to Moshe at the burning bush? Why does He tell Moshe this obvious fact here, at the beginning of our portion? Why does He repeat this phrase 16 more times throughout the book of Shemot? Why does He emphasize this fact by using this phrase 49 times in the book of Vayikra, 5 times in the book of Bamidbar, and 2 more times in the book of Devarim? Does Moshe not remember who this Deity is? Does he forget easily and need constant reminding?
We were slaves to Pharaoh in the land of Egypt. And the Lord, our God, took us out from there with a strong hand and an outstretched forearm. And if the Holy One, blessed be He, had not taken our ancestors from Egypt, behold we and our children and our children's children would [all] be enslaved to Pharaoh in Egypt. And even if we were all sages, all discerning, all elders, all knowledgeable about the Torah, it is a commandment upon us to tell the story of the exodus from Egypt.
