12 For on that night I will go through the land of Egypt, sending death on every first male child, of man and of beast, and judging all the gods of Egypt: I am the Lord. 13 And the blood will be a sign on the houses where you are: when I see the blood I will go over you, and no evil will come on you for your destruction, when my hand is on the land of Egypt. 14 And this day is to be kept in your memories: you are to keep it as a feast to the Lord through all your generations, as an order for ever. 15 For seven days let your food be unleavened bread; from the first day no leaven is to be seen in your houses: whoever takes bread with leaven in it, from the first till the seventh day, will be cut off from Israel. 16 And on the first day there is to be a holy meeting and on the seventh day a holy meeting; no sort of work may be done on those days but only to make ready what is necessary for everyone's food. 17 So keep the feast of unleavened bread; for on this very day I have taken your armies out of the land of Egypt: this day, then, is to be kept through all your generations by an order for ever. 18 In the first month, from the evening of the fourteenth day, let your food be unleavened bread till the evening of the twenty-first day of the month.

Commentary on Exodus 12:1-20
(Read Exodus 12:1-20)
The Lord makes all things new to those whom he delivers from the bondage of Satan, and takes to himself to be his people. The time when he does this is to them the beginning of a new life. God appointed that, on the night wherein they were to go out of Egypt, each family should kill a lamb, or that two or three families, if small, should kill one lamb. This lamb was to be eaten in the manner here directed, and the blood to be sprinkled on the door-posts, to mark the houses of the Israelites from those of the Egyptians. The angel of the Lord, when destroying the first-born of the Egyptians, would pass over the houses marked by the blood of the lamb: hence the name of this holy feast or ordinance. The passover was to be kept every year, both as a remembrance of Israel's preservation and deliverance out of Egypt, and as a remarkable type of Christ. Their safety and deliverance were not a reward of their own righteousness, but the gift of mercy. Of this they were reminded, and by this ordinance they were taught, that all blessings came to them through the shedding and sprinkling of blood. Observe, 1. The paschal lamb was typical. Christ is our passover, 1 Corinthians 5:7,8. Having received Christ Jesus the Lord, we must continually delight ourselves in Christ Jesus. No manner of work must be done, that is, no care admitted and indulged, which does not agree with, or would lessen this holy joy. The Jews were very strict as to the passover, so that no leaven should be found in their houses. It must be a feast kept in charity, without the leaven of malice; and in sincerity, without the leaven of hypocrisy. It was by an ordinance for ever; so long as we live we must continue feeding upon Christ, rejoicing in him always, with thankful mention of the great things he has done for us.
