Care is here taken to perpetuate the remembrance,

I.Of the preservation of Israel's firstborn, when the firstborn of the Egyptians were slain. In memory of that distinguishing favour, and in gratitude for it, the firstborn, in all ages, were to be consecrated to God, as his peculiars (Exo 13:2), and to be redeemed, Exo 13:13. God, who by the right of creation is proprietor and sovereign of all the creatures, here lays claim in particular to the firstborn of the Israelites, by right of protection: Sanctify to me all the firstborn. The parents were not to look upon themselves as interested in their firstborn, till they had first solemnly presented them to God, recognized his title to them, and received them back, at a certain rate, from him again. Note, 1. That which is by special distinguishing mercy spared to us should be in a peculiar manner dedicated to God's honour; at least some grateful acknowledgment, in works of piety and charity, should be made, when our lives, or the lives of our children, have been given us for a prey. 2. God, who is the first and best, should have the first and best, and to him we should resign that which is most dear to us, and most valuable. The firstborn were the joy and hope of their families. Therefore they shall be mine, says God. By this is will appear that we love God best (as we ought) if we are willing to part with that to him which we love best in this world. 3. It is the church of the firstborn that is sanctified to God, Heb 12:23. Christ it the firstborn among many brethren (Rom 8:29), and, by virtue of their union with him, all that are born again, and born from above, are accounted as firstborn. There is an excellency of dignity and power belonging to them; and, if children, then heirs.

II.The remembrance of their coming out of Egypt must also be perpetuated: "Remember this day, Exo 13:3. Remember it by a good token, as the most remarkable day of your lives, the birthday of your nation, or the day of its coming of age, to be no longer under the rod." Thus the day of Christ's resurrection is to be remembered, for in it we were raised up with Christ out of death's house of bondage. The scripture tells us not expressly what day of the year Christ rose (as Moses told the Israelites what day of the year they were brought out of Egypt, that they might remember it yearly), but very particularly what day of the week it was, plainly intimating that, as the more valuable deliverance, and of greater importance, it should be remembered weekly. Remember it, for by strength of hand the Lord brought you out. Note, The more of God and his power appears in any deliverance, the more memorable it is. Now, that it might be remembered,

1.They must be sure to keep the feast of unleavened bread, Exo 13:5-7. It was not enough that they remembered it, but they must celebrate the memorial of it in that way which God had appointed, and use the instituted means of preserving the remembrance of it. So, under the gospel, we must not only remember Christ, but do this in remembrance of him. Observe, How strict the prohibition of leaven is (Exo 13:7); not only no leaven must be eaten, but none must be seen, no, not in all their quarters. Accordingly, the Jews' usage was, before the feast of the passover, to cast all the leavened bread out of their houses: they burnt it, or buried it, or broke it small and scattered it in the wind; they searched diligently with lighted candles in all the corners of their houses, lest any leaven should remain. The care and strictness enjoined in this matter were designed, (1.) To make the feast the more solemn, and consequently the more taken notice of by their children, who would ask, "Why is so much ado made?" (2.) To teach us how solicitous we should be to put away from us all sin, Co1 5:7.

2.They must instruct their children in the meaning of it, and relate to them the story of their deliverance out of Egypt, Exo 13:8. Note, (1.) Care must be taken betimes to instruct children in the knowledge of God. Here is an ancient law for catechising. (2.) It is particularly of great use to acquaint children betimes with the stories of the scripture, and to make them familiar to them. (3.) It is a debt we owe to the honour of God, and to the benefit of our children's souls, to tell them of the great works God has done for his church, both those which we have seen with our eyes done in our day and which we have heard with our ears and our fathers have told us: Thou shalt show thy son in that day (the day of the feast) these things. When they were celebrating the ordinance, they must explain it. Every thing is beautiful in its season. The passover is appointed for a sign, and for a memorial, that the Lord's law may be in thy mouth. Note, We must retain the remembrance of God's works, that we may remain under the influence of God's law. And those that have God's law in their heart should have it in their mouth, and be often speaking of it, the more to affect themselves and to instruct others.

And it shall be for a sign - upon thine hand - This direction, repeated and enlarged Exo 13:16, gave rise to phylacteries or tephillin, and this is one of the passages which the Jews write upon them to the present day. The manner in which the Jews understood and kept these commands may appear in their practice. They wrote the following four portions of the law upon slips of parchment or vellum: Sanctify unto me the first-born, Exodus 13, from Exo 13:2-10 inclusive. And it shall be, when the Lord shall bring thee into the land, Exodus 13, from Exo 13:11-16 inclusive. Hear, O Israel, the Lord our God is one Lord, Deuteronomy 6, from Deu 6:4-9 inclusive. And it shall come to pass, if ye shall hearken diligently, Deuteronomy 11, from Deu 11:13-21 inclusive. These four portions, making in all 30 verses, written as mentioned above, and covered with leather, they tied to the forehead and to the hand or arm.

Those which were for the Head (the frontlets) they wrote on four slips of parchment, and rolled up each by itself, and placed them in four compartments, joined together in one piece of skin or leather. Those which were designed for the hand were formed of one piece of parchment, the four portions being written upon it in four columns, and rolled up from one end to the other. These were all correct transcripts from the Mosaic text, without one redundant or deficient letter, otherwise they were not lawful to be worn. Those for the head were tied on so as to rest on the forehead. Those for the hand or arm were usually tied on the left arm, a little above the elbow, on the inside, that they might be near the heart, according to the command, Deu 6:6 : And these words which I command thee this day shall be in thine heart. These phylacteries formed no inconsiderable part of a Jew's religion; they wore them as a sign of their obligation to God, and as representing some future blessedness. Hence they did not wear them on feast days nor on the Sabbath, because these things were in themselves signs; but they wore them always when they read the law, or when they prayed, and hence they called them תפלין tephillin, prayer, ornaments, oratories, or incitements to prayer. In process of time the spirit of this law was lost in the letter, and when the word was not in their mouth, nor the law in their heart, they had their phylacteries on their heads and on their hands. And the Pharisees, who in our Lord's time affected extraordinary piety, made their phylacteries very broad, that they might have many sentences written upon them, or the ordinary portions in very large and observable letters.

It appears that the Jews wore these for three different purposes: -

1.As signs or remembrancers. This was the original design, as the institution itself sufficiently proves.

2.To procure reverence and respect in the sight of the heathen. This reason is given in the Gemara, Berachoth, chapter i: "Whence is it proved that the phylacteries or tephillin are the strength of Israel? Ans. From what is written, Deu 28:10 : All the people of the earth shall see that thou art called by the name of the Lord (יהוה Yehovah) and they shall be afraid of thee."

3.They used them as amulets or charms, to drive away evil spirits. This appears from the Targum on Sol 8:3 : His left hand is under my head, etc. "The congregation of Israel hath said, I am elect above all people, because I bind my phylacteries on my left hand and on my head, and the scroll is fixed to the right side of my gate, the third part of which looks to my bed-chamber, that demons may not be permitted to injure me.

One of the original phylacteries or תפלין tephillin now lies before me; it is a piece of fine vellum, about eighteen inches long, and an inch and quarter broad. It is divided into four unequal compartments; the letters are very well formed, but written with many apices, after the manner of the German Jews. In the first compartment is written the portion taken from Exo 13:2-10; in the second, Exo 13:11-16; in the third, Deu 6:4-9; in the fourth, Deu 11:13-21, as before related. This had originally served for the hand or arm.

These passages seem to be chosen in vindication of the use of the phylactery itself, as the reader may see on consulting them at large. Bind them for a Sign upon thy Hand; and for Frontlets between thy Eyes; write them upon the Posts of thy House and upon thy Gates; all which commands the Jews take in the most literal sense. To acquire the reputation of extraordinary sanctity they wore the fringes of their garments of an uncommon length. Moses had commanded them, Num 15:38, Num 15:39, to put fringes to the borders of their garments, that when they looked upon even these distinct threads they might remember, not only the law in general but also the very minutiae or smaller parts of all the precepts, rites, and ceremonies belonging to it. As those hypocrites (for such our Lord proves them to be) were destitute of all the life and power of religion within, they endeavored to supply its place with phylacteries and fringes without. The same principles distinguish hypocrites every where, and multitudes of them may be found among those termed Christians as well as among the Jews. It is probably to this institution relative to the phylactery that the words, Rev 14:1, allude: And I looked, and, lo, a hundred and forty-four thousand having his Father's name written on their foreheads. "That is," says Mr. Ainsworth, "as a sign of the profession of God's law; for That which in the Gospel is called his Name, (Mat 12:21), in the prophets is called his Law, (Isa 42:4)." So again antichrist exacts the obedience to his precepts by a mark on men's right hands or on their foreheads, Rev 13:16.

Thou shall therefore keep the ordinance in his season,.... Not the ordinance of the phylacteries, as the Targum of Jonathan, but the ordinance of unleavened bread:

from year to year; every year successively, so long as in force, even unto the coming of the Messiah. It is in the Hebrew text, "from days to days" (c); that is, either year after year, as we understand it; or else the sense is, that the feast of unleavened bread, when the season was come for keeping it, was to be observed every day for seven days running.

(c) "a diebus in dies", V. L. Montanus, Munster, Vatablus, Drusius.

it shall be for a sign unto thee upon thine hand, &c.--There is no reason to believe that the Oriental tattooing--the custom of staining the hands with the powder of Hennah, as Eastern females now do--is here referred to. Nor is it probable that either this practice or the phylacteries of the Pharisees--parchment scrolls, which were worn on their wrists and foreheads--had so early an existence. The words are to be considered only as a figurative mode of expression.

that the Lord's law may be in thy mouth, &c.--that is, that it may be the subject of frequent conversation and familiar knowledge among the people.
