God spoke to Moses, saying,
"Consecrate every firstborn to me - the first one to come from the womb among the Israelites, whether person or animal, is mine."
Moses said to the people, "Always remember this day. This is the day when you came out of Egypt from a house of slavery. God brought you out of here with a powerful hand. Don't eat any raised bread.
"You are leaving in the spring month of Abib.
When God brings you into the land of the Canaanite, the Hittite, the Amorite, the Hivite, and the Jebusite, which he promised to your fathers to give you, a land lavish with milk and honey, you are to observe this service during this month:
"You are to eat unraised bread for seven days; on the seventh day there is a festival celebration to God.
"Only unraised bread is to be eaten for seven days. There is not to be a trace of anything fermented - no yeast anywhere.
"Tell your child on that day: 'This is because of what God did for me when I came out of Egypt.'
