פּירוש אויף במדבר 15:39

וזכרתם את כל מצות ה׳ AND YE SHALL REMEMBER ALL THE COMMANDMENTS OF THE LORD — The ציצית will remind one of all the commandments because the numerical value of the letters of the word ציצית is six hundred, and there are eight threads and five knots in the fringes, so that you have six hundred and thirteen, which is also the number of the commandments of the Torah.

And it will be to you for fringes. Anyone who has a garment with four corners is commanded to always wear it during the day, and not take it off, so that he shall remember. Those that pray with a tallis [only] during the time of prayer do so because of the verses they read during the Shema: “Make for themselves, tzitzis-fringes” and “And it will be to you for fringes.” In my view, however, one has a greater obligation to wear tzitzis at other times than prayer, so that he will remember and not err, and not commit a transgression at any time. During prayer, however, he will likely not transgress.

Scripture states, and that ye go not after your own heart,²²²Verse 39 here. — And since Kol (All) is the all-inclusive attribute it therefore contains all the commandments of the Eternal, and hence the Rabbis have said that the commandment of Tzitzith is of equal importance to the total number of the commandments (Beiur Ha’lvush to Ricanti, quoting the text of Ramban). in order that one should take care concerning it and not err through it.²²⁵I.e., by “mutilating the shoots” of faith, and thereby undermining the principle of the Unity (Tziyoni). See further my Hebrew commentary, p. 254, and see also Vol. I, p. 155. It is for this reason that our Rabbis have interpreted:²²⁶Sifre, Shelach 115; Berachoth 12a. “After your own heart. This refers to scepticism. After which ye use to go astray. This refers to idolatry.” That is to say, through the t’cheileth he should not think [in his heart] of any scepticism or idolatry, but it shall all be unto you for ‘tzitzith’ — that ye may look upon it, and remember. The Rabbis have also said:²²⁶Sifre, Shelach 115; Berachoth 12a. “After your own eyes. This refers to immorality,” similar to that which is written, I am He that knoweth, and am witness, saith the Eternal.²²⁷Jeremiah 29:23. The student learned [in the mysteries of the Cabala] will understand.
In the Midrash of Rabbi Nechunya the son of Hakanah²²⁸Sefer Habahir, 96. it is stated with reference to the verse, and the profit of ‘eretz’ (earth) is ‘bakol’ (in all):²²⁹Ecclesiastes 5:8. “And what is the eretz? It is that from which the heavens were hewn, and it is the Throne of the Holy One, blessed be He, and it is ‘the precious stone,’ and ‘the sea of wisdom,’²³⁰These are Cabalistic synonyms for the all-inclusive attribute of Kol. — The Ma’or V’shamesh [a commentary by Shem Tob ben Gaon on the Cabalistic passages in Ramban’s commentary] continues, on this basis, to explain a basic law in the commandment of Tzitzith, namely, that it applies only at daytime and not at night. Thus he writes: “Hence [i.e., since the t’cheileth in the Fringes represents the all-inclusive attribute, and we are commanded to look upon it, and remember etc.] the commandment applies only at daytime and not at night, for at night physical features are indistinguishable and nothing can be seen in its entirety, while only at daytime the wholeness and perfect harmony of the t’cheileth can be seen and contemplated for its profound meaning].” and corresponding to it is the blue thread in a garment of Fringes, for Rabbi Meir has said: ‘Why was blue chosen? etc.’” [as quoted above].
