God then sent flies, he caused the Egyptions animals to die and he covered the Egyptians in boils.
Next God sent fiery hailstones and Locust that ate everything in sight but Pharaoh still refused.
Moses told Pharaoh that God was going to come through Egypt at around midnight and kill every first born son.
God then spoke to Moses and said, each man is to take a perfect lamb for his family and kill it on the fourteenth day of the month. Then take the blood and put it on the door frames of the houses.
I will kill every first born son of people and animals. When I see the blood on the door frames I will know to pass over your houes. Moses Told the people of Israel what to do and they obeyed.
All the men shall go and take a lamb, and put the blood over the door frame
The Israelites came together and shared the remains of the lamb with their family, this was the first meal of the passover. Similarly we do this at Eucharist, Catholics come together at church and share Communion with each other to remember Jesus and what he did for us.
