The Lord kept watch that night to bring them out of Egypt. So on that same night every year all the Israelites must keep watch. They must do it to honor the Lord for all time to come.
“Always remember this day. You and your children after you must celebrate this day as a feast to honor the Lord. You must do this for all time to come. It is a law that will last forever.
Then Moses said to the people, “Remember this day. It’s the day you came out of Egypt. That’s the land where you were slaves. The Lord used his mighty hand to bring you out of Egypt. Don’t eat anything with yeast in it.
“Celebrate the Feast of Unleavened Bread. For seven days eat bread made without yeast, just as I commanded you. Do it at the appointed time in the month of Aviv. You came out of Egypt in that month.
