In Exodus chapters 10-12, the tension between Pharaoh and Moses intensifies as God unleashes the final plagues upon Egypt. The devastating plague of locusts consumes every plant, followed by an eerie darkness that engulfs the land for three days. Despite the immense suffering, Pharaoh's heart remains hardened. However, the final and most grievous plague—the death of every Egyptian firstborn—forces Pharaoh's hand. God instructs the Israelites to observe the Passover: they are to slaughter a lamb, consume it in haste, and mark their doorposts with its blood. This act ensures their protection from the angel of death. As the wails of grief rise from Egyptian households, Pharaoh urgently expels the Israelites. Thus, after centuries of bondage, the Israelites embark on their journey to freedom, guided by God's mighty hand.
