The plagues that befall Egypt continue as G-d hardens Pharaoh’s heart against the Israelites. A plague of Locusts covers the land, 3 days of total darkness, and the first-born male child and male animal of the Egyptians is slain.
G-d commands the Israelites to create a calendar based on the moon. They are also to have a Passover offering of a lamb (sheep or goat) and spread the blood on their door posts, so they are passed over from the last plague. The meat of the lamb is to be eaten with matzah and bitter herbs.
Pharaoh has had enough, the death of the first born was too much to bear, and he drives the Israelites out of Egypt. The Israelites collect gold and silver, with no time to bake bread they only bring unleavened.
The Israelites are commanded to consecrate their first born, to observe Passover for 7 days each year (removing all leaven from their homes), eating matzah, and recounting the Passover story. Tefillin are also to be worn on the arm and head as a reminder of the Passover and their commitment to G-d.
