And it came to pass, when Pharaoh would hardly let us go,.... Showed great reluctance to it, and with difficulty was prevailed upon to dismiss them:

that the Lord slew all the firstborn in the land of Egypt, both the firstborn of men, and the firstborn of beast: which he did in one night, making use of a destroying angel or angels for that purpose:

therefore I sacrifice to the Lord all that openeth thee matrix, being males; that is, the firstborn of all clean creatures, as oxen, sheep, and goats:

but all the firstborn of my children I redeem; by paying five shekels apiece to the priest for them, as before observed; and this law continues to be observed with the Jews; the manner of which, as related by Leo Modena (i), is as follows,"Thirty days being expired after the birth of the child, they call a priest to them; that is to say, one that is descended of the stock of Aaron, whom the father of the child pleaseth; and so, many people being gathered together at the time appointed, the father of the child bringeth before the priest, in a bowl or basin, a good quantity of gold and silver, and then they give him the child into his arms; the priest then calling the mother of it before him, saith unto her, mistress, is this your son? she answereth, yes; then, replies he, have you never had any child before, either male or female, or have miscarried anyone? she saith unto him, no; then doth the priest say, this child is mine, as being the firstborn; then turning himself toward the father, he asketh him, whether he will redeem it or not? who answereth him, saying, see, here is gold and silver, take your own price; then saith the priest unto him, you will redeem it then? the father answereth, I will redeem it; it shall be so then, saith the priest, this child is mine as being the firstborn, as it is written, Numbers 18:16. I therefore take this in exchange, &c. and so he takes the sum of two French crowns, or thereabout, as he thinks good, and then delivers the child to his father and mother, and this day they make a feasting day.''This custom was used in Christ's time, and was observed with respect to him, Luke 2:27.

לשׁלּחנוּ הקשׁה: "he made hard" (sc., his heart, cf. Exodus 7:3) "to let us go." The sanctification of the first-born is enforced in Exodus 13:16 in the same terms as the keeping of the feast of Mazzoth in Exodus 13:9, with this exception, that instead of לזכרון we have לטוטפת, as in Deuteronomy 6:8, and Deuteronomy 11:18. The word טוטפת signifies neither amulet nor στίγματα, but "binding" or headbands, as is evident from the Chaldee טוטפא armlet (2 Samuel 1:10), טוטפתּא tiara (Esther 8:15; Ezekiel 24:17, Ezekiel 24:23). This command was interpreted literally by the Talmudists, and the use of tephillim, phylacteries (Matthew 23:5), founded upon it;

(Note: Possibly these scrolls were originally nothing more than a literal compliance with the figurative expression, or a change of the figure into a symbol, so that the custom did not arise from a pure misunderstanding; though at a later period the symbolical character gave place more and more to the casual misinterpretation. On the phylacteries generally, see my Archologie and Herzog's Cycl.)

the Caraites, on the contrary, interpreted it figuratively, as a proverbial expression for constant reflection upon, and fulfilment of, the divine commands. The correctness of the latter is obvious from the words themselves, which do not say that the commands are to be written upon scrolls, but only that they are to be to the Israelites for signs upon the hand, and for bands between the eyes, i.e., they are to be kept in view like memorials upon the forehead and the hand. The expression in Deuteronomy 6:8, "Thou shalt bind them for a sign upon thine hand, and they shall be as frontlets between thine eyes," does not point at all to the symbolizing of the divine commands by an outward sign to be worn upon the hand, or to bands with passages of the law inscribed upon them, to be worn on the forehead between the eyes; nor does the "advance in Deuteronomy 6:8 from heart to word, and from word to hand or act," necessarily lead to the peculiar notion of Schultz, that "the sleeve and turban were to be used as reminders of the divine commands, the former by being fastened to the hand in a peculiar way, the latter by an end being brought down upon the forehead." The line of thought referred to merely expresses the idea, that the Israelites were not only to retain the commands of God in their hearts, and to confess them with the mouth, but to fulfil them with the hand, or in act and deed, and thus to show themselves in their whole bearing as the guardians and observers of the law. As the hand is the medium of action, and carrying in the hand represents handling, so the space between the eyes, or the forehead, is that part of the body which is generally visible, and what is worn there is worn to be seen. This figurative interpretation is confirmed and placed beyond doubt by such parallel passages as Proverbs 3:3, "Bind them (the commandments) about thy neck; write them upon the tables of thine heart" (cf. Proverbs 3:21, Proverbs 3:22, Exodus 4:21; Exodus 6:21-22; Exodus 7:3).

And it came to pass, when Pharaoh would hardly let us go, that the LORD slew all the firstborn in the land of Egypt, both the firstborn of man, and the firstborn of beast: therefore I sacrifice to the LORD all that openeth the matrix, being males; but all the firstborn of my children I redeem.

13:11-16 The firstlings of beast not used in sacrifice, were to be changed for others so used, or they were to be destroyed. Our souls are forfeited to God's justice, and unless ransomed by the sacrifice of Christ, will certainly perish. These institutions would continually remind them of their duty, to love and serve the Lord. In like manner, baptism and the Lord's supper, if explained and attended to, would remind us, and give us occasion to remind one another of our profession and duty.
