Where is the introduction of Passover in the Bible?
The introduction of Passover is found in Exodus chapter 12, a benchmark chapter where the institution of Passover is given. The Lord spoke to Moses and Aaron in the land of Egypt, establishing the first month as the beginning of months. This chapter records the original Passover ordinance.
Les explains that Exodus chapter 12 is a benchmark chapter, much like Genesis chapter 12, because here we have the introduction of Passover. He notes that Orthodox Jews still practice Passover, cleansing their houses of leaven from top to bottom, and it all goes back to this institution in Exodus chapter 12. The chapter opens with the Lord speaking to Moses and Aaron in the land of Egypt, saying that month—now called April—shall be the beginning of months.
