Exodus 13:1 says, And the LORD spake unto Moses, saying,  Then verse two adds, Sanctify unto me all the firstborn, whatsoever openeth the womb among the children of Israel, both of man and of beast: it is mine.  God spoke to Moses once again and told him to dedicate the first born of all the people and animals of the nation of Israel to God.  God had spared all their first born when He destroyed the first born of Egypt, so it was a reasonable request that they be dedicated to God.  God spares us from the penalty of sin when we accept Christ as our Savior and Lord, so it is a reasonable request that we dedicate ourselves to living for Him.  Verse three declares, And Moses said unto the people, Remember this day, in which ye came out from Egypt, out of the house of bondage; for by strength of hand the LORD brought you out from this place: there shall no leavened bread be eaten.  The day that the people of Israel were delivered was to be remembered each year by eating unleavened bread.  We as followers of Christ today celebrate Easter for the same reason.  Easter is a celebration of the day that God delivered us from the power of sin and death.  Verse four adds, This day came ye out in the month Abib.  This verse specifies the time on their calendar of that day.  Verse five continues, And it shall be when the LORD shall bring thee into the land of the Canaanites, and the Hittites, and the Amorites, and the Hivites, and the Jebusites, which he sware unto thy fathers to give thee, a land flowing with milk and honey, that thou shalt keep this service in this month.  God told Moses that when God brought them to the land flowing with milk and honey that they were still to observe this day.  Sometimes, when God really prospers us, we tend to forget about serving Him, but we should always remember Who God is and what He wants of us as His followers.  Verse six states, Seven days thou shalt eat unleavened bread, and in the seventh day shall be a feast to the LORD.  The people of Israel were to eat unleavened bread for a week, then have a feast to the LORD.  Verse seven adds, Unleavened bread shall be eaten seven days; and there shall no leavened bread be seen with thee, neither shall there be leaven seen with thee in all thy quarters. Not only were they to eat unleavened bread, they were to have no leaven in their house.  This would remove any temptation to use it.  When we accept Christ as our Savior and Lord, we should attempt to remove all things from our lives that could lead us into temptation.  Verse eight continues,  And thou shalt shew thy son in that day, saying, This is done because of that which the LORD did unto me when I came forth out of Egypt. They were to teach their children why this was done, just as we are to tell our children about salvation through Christ today.  Verse nine states, And it shall be for a sign unto thee upon thine hand, and for a memorial between thine eyes, that the LORD’s law may be in thy mouth: for with a strong hand hath the LORD brought thee out of Egypt.  They were to keep the memory of what God did before them at all times, just as we are to with the memory of what God did for us when Christ died for us,  Verse ten concludes, Thou shalt therefore keep this ordinance in his season from year to year. This was to be a yearly celebration.
