Then the Lord said to Moses, “Dedicate to Me every firstborn among the Israelites. The first offspring to be born, of both humans an animals, belongs to Me.”
So Moses said to the people, “This is a day to remember forever-the day you left Egypt, the place of your slavery. today the Lord has brought you out by the power of His mighty hand. (Remember, eat not food containing yeast.) On this day, in early spring, in the day of Abib, you have been set free. You must celebrate this event in this month each year after the Lord brings you into the land of the Canaanites, Hitites, Amorites, Hivites, and Jebusites. (He swore to your ancestors that He would give you this land-a land flowing with milk and honey.) For seven days, the bread you eat must be made without yeast. Then on the seventh day, celebrate a feast to the Lord. Eat bread without any yeast during those seven days or any yeast at all found within the borders of your land during this time. (vv 1-7, NLT).
