Exodus 11 - 12

Exodus 11-12 narrates the final plague of three days of darkness, which failed to make Pharaoh relent, and the death of the firstborns in Egypt, including Pharaoh's own firstborn. The Israelites were instructed to mark their doors with lamb's blood and eat unleavened bread and bitter herbs, while the Passover feast and week-long Feast of Unleavened Bread were to be celebrated as memorial events throughout the generations. The Passover ceremony represents Christian life without malice and wickedness and Christ's protection of his followers, and symbolizes the avoidance of spiritual leaven and the embrace of sincerity and truth.
