Charles Spurgeon Commentary Exodus 12:13-20

"And the blood shall be to you for a token upon the houses where ye are: and when I see the blood, I will pass over you, and there shall no plague be upon you to destroy you, when I smite the land of Egypt. And this day shall be unto you for a memorial, and ye shall keep it a feast to Jehovah: throughout your generations ye shall keep it a feast by an ordinance for ever. Seven days shall ye eat unleavened bread; even the first day ye shall put away leaven out of your houses: for whosoever eateth leavened bread from the first day until the seventh day, that soul shall be cut off from Israel. And in the first day there shall be to you a holy convocation, and in the seventh day a holy convocation; no manner of work shall be done in them, save that which every man must eat, that only may be done by you. And ye shall observe the [feast of] unleavened bread; for in this selfsame day have I brought your hosts out of the land of Egypt: therefore shall ye observe this day throughout your generations by an ordinance for ever. In the first [month], on the fourteenth day of the month at even, ye shall eat unleavened bread, until the one and twentieth day of the month at even. Seven days shall there be no leaven found in your houses: for whosoever eateth that which is leavened, that soul shall be cut off from the congregation of Israel, whether he be a sojourner, or one that is born in the land. Ye shall eat nothing leavened; in all your habitations shall ye eat unleavened bread." — Exodus 12:13-20 (ASV)

And the plague shall not be upon you to destroy you, when I smite the land of Egypt. And this day shall be unto you for a memorial; and you shall keep it a feast to the LORD throughout your generations; you shall keep it a feast by an ordinance forever. Seven days shall you eat unleavened bread; even the first day you shall put away leaven out of your houses: for whosoever eats leavened bread from the first day until the seventh day, that soul shall be cut off from Israel. And in the first day there shall be an holy convocation, and in the seventh day there shall be an holy convocation to you; no manner of work shall be done in them, save that which every man must eat, that only may be done of you. And you shall observe the feast of unleavened bread; for in this selfsame day have I brought your armies out of the land of Egypt: therefore shall you observe this day in your generations by an ordinance forever. In the first month, on the fourteenth day of the month at even, you shall eat unleavened bread, until the one and twentieth day of the month at even. Seven days shall there be no leaven found in your houses: for whosoever eats that which is leavened, even that soul shall be cut off from the congregation of Israel, whether he be a stranger, or born in the land. You shall eat nothing leavened; in all your habitations shall you eat unleavened bread.

Thus we see God instituting a commemoration of the deliverance of his people out of Egypt. How much more ought you and I, with joyful gladness, to remember the deliverance of our soul from the slavery of sin and Satan! Let us never forget it. I should like to refresh the memories of bygone times with you who know the Lord. May the Lord help you now, with deepest gratitude, to recollect the day when first you saw your Savior, when the yoke was taken from your neck and the burden from your shoulder. Glory be to the delivering Lord!
