The LORD spoke to Moses,
"Set apart every firstborn male for me. Every firstborn male offspring among the Israelites is mine, whether human or animal."
Then Moses said to the people, "Remember this day--the day when you left Egypt, the land of slavery. The LORD used his mighty hand to bring you out of there. Don't eat anything made with yeast.
Today, in the month of Abib, you are leaving Egypt.
The LORD swore to your ancestors that he would give you the land of the Canaanites, Hittites, Amorites, Hivites, and Jebusites. When he brings you into that land flowing with milk and honey, you must observe this ceremony in this month.
"For seven days you must eat unleavened bread. The seventh day will be a pilgrimage festival in the LORD's honor.
Only unleavened bread should be eaten during these seven days. No sourdough or yeast should be seen anywhere in your territory.
On that day tell your children, 'We do this because of what the LORD did for us when we left Egypt.'
