Here we have,

I.Further directions concerning the dedicating of their firstborn to God. 1. The firstlings of their cattle were to be dedicated to God, as part of their possessions. Those of clean beasts - calves, lambs, and kids - if males, were to be sacrificed, Exo 22:30; Num 18:17, Num 18:18. Those of unclean beasts, as colts, were to be redeemed with a lamb, or knocked on the head. For whatsoever is unclean (as we all are by nature), if it be not redeemed, will be destroyed, Exo 13:11, Exo 13:13. 2. The firstborn of their children were to be redeemed, and by no means sacrificed, as the Gentiles sacrificed their children to Moloch. The price of the redemption of the firstborn was fixed by the law (Num 18:16) at five sheckles. We were all obnoxious to the wrath and curse of God; by the blood of Christ we are redeemed, that we may be joined to the church of the firstborn. They were to redeem their children, as well as the firstlings of the unclean beasts, for our children are by nature polluted. Who can bring a clean thing out of an unclean?

II.Further directions concerning the catechising of their children, and all those of the rising generation, from time to time, in this matter. It is supposed that, when they saw all the firstlings thus devoted, they would ask the meaning of it, and their parents and teachers must tell them (Exo 13:14-16) that God's special propriety in their firstborn, and all their firstlings, was founded in his special preservation of them from the sword of the destroying angel. Being thus delivered, they must serve him. Note, 1. Children should be directed and encouraged to ask their parents questions concerning the things of God, a practice which would be perhaps of all others the most profitable way of catechising; and parents must furnish themselves with useful knowledge, that they may be ready always to give an answer to their enquiries. If ever the knowledge of God cover the earth, as the waters do the sea, the fountains of family-instruction must first be broken up. 2. We should all be able to show cause for what we do in religion. As sacraments are sanctified by the word, so they must be explained and understood by it. God's service is reasonable, and it is then acceptable when we perform it intelligently, knowing what we do and why we do it. 3. It must be observed how often it is said in this chapter that by strength of hand (Exo 13:3, Exo 13:14, Exo 13:16), with a strong hand (Exo 13:9), the Lord brought them out of Egypt. The more opposition is given to the accomplishment of God's purposes the more is his power magnified therein. It is a strong hand that conquers hard hearts. Sometimes God is said to work deliverance not by might nor power (Zac 4:6), not by such visible displays of his power as that recorded here. 4. Their posterity that should be born in Canaan are directed to say, The Lord brought us out of Egypt, Exo 13:14, Exo 13:16. Mercies to our fathers are mercies to us; we reap the benefit of them, and therefore must keep up a grateful remembrance of them. We stand upon the bottom of former deliverances, and were in the loins of our ancestors when they were delivered. Much more reason have we to say that in the death and resurrection of Jesus Christ we were redeemed.

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.

That thou shalt set apart unto the Lord all that openeth the matrix,.... Or "the womb", as in Exo 13:2, and this phrase, "set apart", explains the word "sanctify" there, and shows that it signifies the separating of such to the use and service of God, causing it to "pass", as the word (d) here used signifies, from a man's own power and use, to be the Lord's only:

and every firstling that cometh from a beast which thou hast; or "even every firstling" (e), explaining what is meant by what opens the matrix or womb, even every firstborn of a beast; though Jarchi interprets it of an abortion, what comes before its time, that this also should be set apart to the Lord; this must be understood of the firstlings of clean creatures, fit for food and sacrifice, such as the firstlings of cows, sheep, and goats, Num 18:17 as distinguished from unclean ones in the following verse:

the males shall be the Lord's; which explains what sort of firstborn of man and beast were to be set apart for his use, not females, though the first that opened the womb; but males.

(d) "et transire facies", Pagninus, Montanus, Fagius, Vatablus, Drusius, Cartwright; so Ainsworth. (e) "etiam quicunque vel quicquid aperuerit", Junius & Tremellius, Piscator, Ainsworth.

FIRSTLINGS OF BEASTS. (Exo 13:11-16)

every firstling, &c.--the injunction respecting the consecration of the first-born, as here repeated, with some additional circumstances. The firstlings of clean beasts, such as lambs, kids, and calves, if males, were to be devoted to God and employed in sacrifice. Those unclean beasts, as the ass's colt, being unfit for sacrifice, were to be redeemed (Num 18:15).
