The Passover
In the book of Exodus, God sends ten plagues upon Egypt to compel Pharaoh to release the Israelites from slavery. The final plague results in the death of every firstborn in the land, but the Israelites are spared when they apply the blood of a sacrificed lamb to their doorposts as instructed by God. This event marks the institution of the Passover, a sacred meal eaten in haste that commemorates God's protection and deliverance. Its significance extends throughout Scripture as a foreshadowing of redemption and the establishment of a covenant people freed to worship the Lord.
Meanwhile in the World
Egypt is at the height of its New Kingdom power under pharaohs like Thutmose III and Ramesses II. The Hittite Empire controls Anatolia. The Late Bronze Age collapse is approaching. Troy exists as a real city. This is the time of the Amarna letters and international diplomacy.
