The book of Exodus is full of familiar stories, including the story of Moses, the plagues of Egypt, the Passover, parting of the Red Sea, Mount Sinai, the Ten Commandments, and the golden calf.
The major event in Exodus is the Passover, which is our clearest Old Testament picture of our individual salvation through faith in the shed blood of our Lord Jesus Christ.
God commanded the community of Israel to take a year-old male lamb without defect, slaughter them at twilight, and spread the blood on the sides and tops of the doorframes.
That night God struck down every firstborn of every household that wasn’t covered by the blood of the lamb.
Safety came not from being an Israelite but from applying the blood. Israelite families who didn’t obey God by putting the blood on their doorframes lost their firstborn. Egyptians who obeyed and spread blood on their doorframes were spared.
Genesis 8:4 tells us that Noah’s ark came to rest on the 17th day of the 7th month, which we learn in Exodus 13:4 is the month of Abib (later called Nisan).
God tells Moses in Exodus 12:6 to slaughter the lambs on the 14th day of the month. And in 12:14, God tells the Israelites to celebrate the day (14th of Nisan) for generations to come.
In Luke 22:1-20, Jesus is crucified on the Passover, the 14th of Nisan. He rose three days later, the 17th of Nisan (or Abib), the same day the ark came to rest.
