We start our journey together: we were all slaves.  Our obligation is to tell our story.

וּלְמַעַן תְּסַפֵּר בְּאָזְנֵי בִנְךָ וּבֶן-בִּנְךָ, אֵת אֲשֶׁר הִתְעַלַּלְתִּי בְּמִצְרַיִם, וְאֶת-אֹתֹתַי, אֲשֶׁר-שַׂמְתִּי בָם; וִידַעְתֶּם, כִּי-אֲנִי יְהוָה

(Exodus 10:2)

“In order that you (singular) may tell your child and your grandchild the things I have done in Egypt, and the signs that I have done among them, that you (plural) may know that I am the Lord.”

Our history is continually intertwined. 

“One individual telling the story to his (her) child or grandchild, many in the end will understand the meaning of the Exodus of Egypt.” (Nechama Leibowitz)

Yet, we are humbled for if we were the wisest, smartest, most savvy individuals, we would still have an obligation to discuss our Exodus from Egypt.
