Escaping Egypt is about the nation of Israel finding freedom & starting their journey to the "Promised Land" This was at the very first "Passover" which was held on their very first "New Years Eve"... & it turned out to be quite a celebration then & ever since. As members of the Body of Christ we celebrate this also at Easter, and even more often when we participate in "The Lords Supper" a remembrance & celebration of that New Years Eve, before Jesus bore the sin of the whole world.
