And it shall be unto you for a fringe,.... The blue ribbon or lace shall be in or upon the fringe to fasten it:

that ye may look upon it; the blue lace making the whole the more conspicuous: from hence the Jews gather, that the night is not the time for wearing fringe, which lessens the sight, and it is not so easily seen; and that night garments are not obliged to have the fringe on them; and yet, they say, a blind man is bound to wear it, because, though he cannot see it, others can (g):

and remember all the commandments of the Lord, and do them: this is the general use, end, and design of the fringes, that upon sight of them they might be put in mind of the commandments and put upon the practice of them; these being at the four corners of their vestments, let them look which way they would downwards, before or behind, or on either side, they could not but see them: and the many threads in them might put them in mind of the many precepts they were to observe; and the white colour, the purity and holiness of them; and the blue or sky-coloured lace might lead them to observe the heavenly original of them; or being of a purple colour rather, might direct them to the blood of Christ, for the remission of the transgressions of them: the Jews have many fanciful things about the use and virtue of these fringes, not worthy of notice; and they say, that such who are careful to observe this law of the fringe, are worthy to see the face of the divine Majesty, and will be preserved from evil spirits (h):

and that ye seek not after your own heart and your own eyes; to have and enjoy, and do those things, in matters of worship, which were of their own devising, and pleasing in their sight, as well as in moral things, what were agreeable to their carnal hearts, and make for the gratification of their senses:

after which ye use to go a whoring; which seems to restrain the sense pretty much to idolatry, to false and superstitious worship, which are often in Scripture expressed by fornication and whoredom; though other sins and lusts also are sometimes signified by the same words.

"And it shall be to you for a tassel," i.e., the fastening of the tassel with the dark blue thread to the corners of your garments shall be to you a tassel, "that ye, when ye see it, may remember all the commandments of Jehovah, and do them; and ye shall not stray after your hearts and your eyes, after which ye go a whoring." The zizith on the sky-blue thread was to serve as a memorial sign to the Israelites, to remind them of the commandments of God, that they might have them constantly before their eyes and follow them, and not direct their heart and eyes to the things of this world, which turn away from the word of God, and lead astray to idolatry (cf. Proverbs 4:25-26). Another reason for these instructions, as is afterwards added in Numbers 15:40, was to remind Israel of all the commandments of the Lord, that they might do them and be holy to their God, and sanctify their daily life to Him who had brought them out of Egypt, to be their God, i.e., to show Himself as God to them.

And it shall be unto you for a fringe, that ye may look upon it, and remember all the commandments of the LORD, and do them; and that ye seek not after your own heart and your own eyes, after which ye use to go a {i} whoring:

(i) By leaving God's commandments and following your own fantasies.

15:39 For a fringe - That is, the ribband, shall be unto you, shall serve you for a fringe, to render it more visible by its distinct colour, whereas the fringe without this was of the same piece and colour with the garment, and therefore less observeable. That ye seek not - Or, enquire not for other rules and ways of serving me than I have prescribed you. Your own heart, and eyes - Neither after the devices of your own hearts, as Nadab and Abihu did when they offered strange fire; nor after the examples of others which your eyes see, as you did when you were set upon worshipping a calf after the manner of Egypt. The phylacteries worn by the Pharisees in our Lord's time, were a different thing from these. Those were of their own invention: these were a divine institution.

15:37-41 The people are ordered by the Lord to make fringes on the borders of their garments. The Jews were distinguished from their neighbours in their dress, as well as in their diet, and thus taught not to be conformed to the way of the heathen in other things. They proclaimed themselves Jews wherever they were, as not ashamed of God and his law. The fringes were not appointed for trimming and adorning their clothes, but to stir up their minds by way of remembrance, 2Pe 3:1. If they were tempted to sin, the fringe would warn them not to break God's commandments. We should use every means of refreshing our memories with the truths and precepts of God's word, to strengthen and quicken our obedience, and arm our minds against temptation. Be holy unto your God; cleansed from sin, and sincerely devoted to his service; and that great reason for all the commandments is again and again repeated, I am the Lord your God.
