The upper door post - Or lintel, Exodus 12:23. This direction was understood by the Hebrews to apply only to the first Passover: it was certainly not adopted in Palestine. The meaning of the sprinkling of blood is hardly open to question. It was a representation of the offering of the life, substituted for that of the firstborn in each house, as an expiatory and vicarious sacrifice.

Take of the blood, and strike it on the two side posts - This was to be done by dipping a bunch of hyssop into the blood, and thus sprinkling it upon the posts, etc.; see Exodus 12:22. That this sprinkling of the blood of the paschal lamb was an emblem of the sacrifice and atonement made by the death of Jesus Christ, is most clearly intimated in the sacred writings, 1 Peter 1:2; Hebrews 9:13, Hebrews 9:14; Hebrews 8:10. It is remarkable that no blood was to be sprinkled on the threshold, to teach, as Mr. Ainsworth properly observes, a reverent regard for the blood of Christ, that men should not tread under foot the Son of God, nor count the blood of the covenant wherewith they were sanctified an unholy thing; Hebrews 10:29.

And they shall take of the blood,.... Of the lamb, being received into a basin, Exodus 12:22,

and strike it on the two side posts; with a bunch of hyssop dipped into it:

and on the upper doorpost of the houses, wherein they shall eat it; but not on the posts of those houses, the inhabitants of which joined with their neighbours in eating it; though Levi Ben Gersom thinks they were sprinkled as the rest; but to what purpose, when there were no Israelites, and no firstborn in them? the two side posts were the posts of a folding door, on which the two folds were hung, and the upper doorpost is what is afterwards called the lintel, Exodus 12:23 and has its name in Hebrew from looking out; for, as Aben Ezra says, there was a window over the door, as is the custom throughout the whole country of the Ishmaelites or Arabians; and so Schindler says (o), which perhaps he took from him, that the word signifies either a lintel, or a little window over the door, through which it might be seen who called or knocked at the door; and adds, in Egypt, as now in Arabia, there were windows over the doors of houses. The sprinkling the blood of the paschal lamb was typical of the sprinkling of the blood of Christ upon the hearts and consciences of his people, and of their peace, safety, and security by it from the wrath of God, and the vengeance of divine justice; of the further use of this rite, see Exodus 12:22, Aben Ezra mentions it as the opinion of some, that the sprinkling of the blood on those places was to show that they slew the abomination of the Egyptians openly; but he himself gives a much better reason for this rite, namely, that it was to be a propitiation for everyone that ate in the house, and was a sign to the destroyer, that he might look upon it in like manner, as it is said Ezekiel 9:4, "set a mark, &c." this seems to be peculiar to the passover in Egypt, and was not used in later times.

Some of the blood was to be put (נתן as in Leviticus 4:18, where יתּן is distinguished from הזּה, to sprinkle, in Leviticus 4:17) upon the two posts and the lintel of the door of the house in which the lamb was eaten. This blood was to be to them a sign (Exodus 12:13); for when Jehovah passed through Egypt to smite the first-born, He would see the blood, and would spare these houses, and not permit the destroyer to enter them (Exodus 12:13, Exodus 12:23). The two posts with the lintel represented the door (Exodus 12:23), which they surrounded; and the doorway through which the house was entered stood for the house itself, as we may see from the frequent expression "in thy gates," for in thy towns (Exodus 20:10; Deuteronomy 5:14; Deuteronomy 12:17, etc.). The threshold, which belonged to the door quite as much as the lintel, was not to be smeared with blood, in order that the blood might not be trodden under foot. But the smearing of the door-posts and lintel with blood, the house was expiated and consecrated on an altar. That the smearing with blood was to be regarded as an act of expiation, is evident from the simple fact, that a hyssop-bush was used for the purpose (Exodus 12:22); for sprinkling with hyssop is never prescribed in the law, except in connection with purification in the sense of expiation (Leviticus 14:49.; Numbers 19:18-19). In Egypt the Israelites had no common altar; and for this reason, the houses in which they assembled for the Passover were consecrated as altars, and the persons found in them were thereby removed from the stroke of the destroyer. In this way the smearing of the door-posts and lintel became a sign to Israel of their deliverance from the destroyer. Jehovah made it so by His promise, that He would see the blood, and pass over the houses that were smeared with it. Through faith in this promise, Israel acquired in the sign a firm pledge of its deliverance. The smearing of the doorway was relinquished, after Moses (not Josiah, as Vaihinger supposes, cf. Deuteronomy 16:5-6) had transferred the slaying of the lambs to the court of the sanctuary, and the blood had been ordered to be sprinkled upon the altar there.

And they shall take of the blood, and strike it on the two side posts and on the upper door post of the houses, wherein they shall eat it.

7. take of the blood, and strike it on the two side-posts, &c.-as a sign of safety to those within. The posts must be considered of tents, in which the Israelites generally lived, though some might be in houses. Though the Israelites were sinners as well as the Egyptians, God was pleased to accept the substitution of a lamb-the blood of which, being seen sprinkled on the doorposts, procured them mercy. It was to be on the sideposts and upper doorposts, where it might be looked to, not on the threshold, where it might be trodden under foot. This was an emblem of the blood of sprinkling (Heb 12:24; 10:29).

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, 1Co 5:7. Christ is the Lamb of God, Joh 1:29; often in the Revelation he is called the Lamb. It was to be in its prime; Christ offered up himself in the midst of his days, not when a babe at Bethlehem. It was to be without blemish; the Lord Jesus was a Lamb without spot: the judge who condemned Christ declared him innocent. It was to be set apart four days before, denoting the marking out of the Lord Jesus to be a Saviour, both in the purpose and in the promise. It was to be slain, and roasted with fire, denoting the painful sufferings of the Lord Jesus, even unto death, the death of the cross. The wrath of God is as fire, and Christ was made a curse for us. Not a bone of it must be broken, which was fulfilled in Christ, Joh 19:33, denoting the unbroken strength of the Lord Jesus. 2. The sprinkling of the blood was typical. The blood of the lamb must be sprinkled, denoting the applying of the merits of Christ's death to our souls; we must receive the atonement, Ro 5:11. Faith is the bunch of hyssop, by which we apply the promises, and the benefits of the blood of Christ laid up in them, to ourselves. It was to be sprinkled on the door-posts, denoting the open profession we are to make of faith in Christ. It was not to be sprinkled upon the threshold; which cautions us to take heed of trampling under foot the blood of the covenant. It is precious blood, and must be precious to us. The blood, thus sprinkled, was a means of preserving the Israelites from the destroying angel, who had nothing to do where the blood was. The blood of Christ is the believer's protection from the wrath of God, the curse of the law, and the damnation of hell, Ro 8:1. 3. The solemn eating of the lamb was typical of our gospel duty to Christ. The paschal lamb was not to be looked upon only, but to be fed upon. So we must by faith make Christ our own; and we must receive spiritual strength and nourishment from him, as from our food, see Joh 6:53,55. It was all to be eaten; those who by faith feed upon Christ, must feed upon a whole Christ; they must take Christ and his yoke, Christ and his cross, as well as Christ and his crown. It was to be eaten at once, not put by till morning. To-day Christ is offered, and is to be accepted while it is called to-day, before we sleep the sleep of death. It was to be eaten with bitter herbs, in remembrance of the bitterness of their bondage in Egypt; we must feed upon Christ with sorrow and brokenness of heart, in remembrance of sin. Christ will be sweet to us, if sin be bitter. It was to be eaten standing, with their staves in their hands, as being ready to depart. When we feed upon Christ by faith, we must forsake the rule and the dominion of sin; sit loose to the world, and every thing in it; forsake all for Christ, and reckon it no bad bargain, Heb 13:13,14. 4. The feast of unleavened bread was typical of the Christian life, 1Co 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.
