Death of the Firstborn (Exodus 11) and The Passover Instituted (Exodus 12)

     Exodus  (Chapter 11)  Afterward he will let you go from here.  When he lets you go, he will surely drive you out of here altogether.  Speak  now in the  hearing of the people, and let every man ask from his  neighbor and every woman from her neighbor, articles of  silver and articles of gold.

     Exodus (Chapter 12) This month shall be your beginning of months; it shall be the first month of the year to you.
