Provision had been just now made by the law for the pardon of sins of ignorance and infirmity; now here is an expedient provided for the preventing of such sins. They are ordered to make fringes upon the borders of their garments, which were to be memorandums to them of their duty, that they might not sin through forgetfulness. 1. The sign appointed is a fringe of silk, or thread, or worsted, or the garment itself ravelled at the bottom, and a blue riband bound on the top of it to keep it tight, v. 38. The Jews being a peculiar people, they were thus distinguished from their neighbours in their dress, as well as in their diet, and taught by such little instances of singularity not to be conformed to the way of the heathen in greater things. Thus likewise they proclaimed themselves Jews wherever they were, as those that were not ashamed of God and his law. Our Saviour, being made under the law, wore these fringes; hence we read of the hem or border, of his garment, Matt. ix. 20. These borders the Pharisees enlarged, that they might be thought more holy and devout than other people. The phylacteries were different things; these were their own invention, the fringes were a divine institution. The Jews at this day wear them, saying, when they put them on, Blessed be he who has sanctified us unto himself, and commanded us to wear fringes. 2. The intention of it was to remind them that they were a peculiar people. They were not appointed for the trimming and adorning of their clothes, but to stir up their pure minds by way of remembrance (2 Pet. iii. 1), that they might look upon the fringe and remember the commandments. Many look upon their ornaments to feed their pride, but they must look upon these ornaments to awaken their consciences to a sense of their duty, that their religion might constantly beset them, and that they might carry it about with them, as they did their clothes, wherever they went. If they were tempted to sin, the fringe would be a monitor to them not to break God's commandments: If a duty was forgotten to be done in its season, the fringe would remind them of it. This institution, though it is not an imposition upon us, is an instruction to us, always to remember the commandments of the Lord our God, that we may do them, to treasure them up in our memories, and to apply them to particular cases as there is occasion to use them. It was intended particularly to be a preservative from idolatry: that you seek not after your own heart, and your own eyes, in your religious worship. Yet it may extend also to the whole conversation, for nothing is more contrary to God's honour, and our own true interest, than to walk in the way of our heart and in the sight of our eyes; for the imagination of the heart is evil, and so is the lust of the eyes.
After the repetition of some ceremonial appointments, the chapter closes with that great and fundamental law of religion, Be holy unto your God, purged from sin, and sincerely devoted to his service; and that great reason for all the commandments is again and again inculcated, I am the Lord your God. Did we more firmly believe, and more frequently and seriously consider, that God is the Lord, and our God and Redeemer, we should see ourselves bound in duty, interest, and gratitude, to keep all his commandments. __________________________________________________________________
