(37) The Eternal said to Moses as follows: (38) Speak to the Israelite people and instruct them to make for themselves fringes on the corners of their garments throughout the ages; let them attach a cord of blue to the fringe at each corner. (39) That shall be your fringe; look at it and recall all the commandments of the Eternal and observe them, so that you do not follow your heart and eyes in your lustful urge. (40) Thus you shall be reminded to observe all My commandments and to be holy to your God. (41) I the Eternal am your God, who brought you out of the land of Egypt to be your God: I, the Eternal your God.
וזכרתם את כל מצות ה׳ AND YE SHALL REMEMBER ALL THE COMMANDMENTS OF THE Eternal— 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.
The Gemara clarifies: Granted, these three are mentioned explicitly: The yoke of mitzvot is mentioned in the portion of ritual fringes, as it is written: “And you shall look upon them and remember all the mitzvot of the Lord and you shall do them” (Numbers 15:39). Ritual fringes are mentioned explicitly, as it is written: “And they will make for themselves ritual fringes” (Numbers 15:38). The exodus from Egypt is also mentioned explicitly, as it is written: “I am the Eternal, your God, who took you out from the Land of Egypt” (Numbers 15:41). But where do we derive the other elements mentioned above: Admonition against the opinions of the heretics, admonition against thoughts of transgressions of licentiousness, and admonition against thoughts of idolatry?
