Yahweh tells the Israelites to consecrate their firstborn sons and livestock and celebrate a festival to commemorate their deliverance from Egypt. The Israelites take a circuitous route to draw Pharaoh’s army after them.
Exodus 12: The Passover and the Festival of Unleavened Bread
Yahweh gives instructions to Moses and Aaron for the Israelites to prepare a meal and mark their houses with blood. He kills all the firstborn humans and livestock in Egypt, passing over the homes marked with blood. The Israelites prepare to leave Egypt, collecting gold, silver and clothing from their neighbors and preparing unleavened dough. Yahweh gives instructions to for future generations to celebrate this festival in remembrance.
Exodus 9: The Plague of Livestock
Yahweh sends a plague on the Egyptian livestock, killing all that was in the fields except in the land of Goshen. He then sends boils and hail. Pharaoh still refuses to let the Israelites go.
