It is at this point that the Jews' trouble begins. Joseph gave so much to the people of Egypt and prevented their downfall, but within a generation, all was forgotten. It is easy in life to have a "what have you done for me lately" attitude, remembering only those events and favors which have happened in the recent past.
However, sometimes those in our lives cannot be there for us in every moment at their highest capacity. Often the people we rely on the most get tired, worn out, and might actually need to receive help from us. Had the Egyptians kept in mind all that Joseph and his brethren did for the Egyptians, a productive and respectful relationship could have continued and developed further.
When we remember the Exodus, we remember the distant past as if we were there in real time. Just as we remember the heroism of Moses, Miriam, the people Israel, and God in the distant past, we should also remember the great contributions and small kindnesses shown to us a while back. This type of remembering is what keeps relationships healthy, holy, and balanced.
A Happy December 25th and a Shabbat Shalom from Tel Aviv!
