Мидраш к Бамидбар 15:40

"And make for yourselves tzitzit" (Numbers 15:38): this is written (Psalms 97:11) "Light is sown for the righteous, etc" (Isaiah 42:21) "God desires [His servant's] vindication". The Holy Blessed One sowed the Torah and the commandments in order that the Jews would inherit them to life in the world to come. And God did not leave a thing in the world without giving a mitzvah about it to the Jews. Going out to plough: (Deuteronomy 22:10) "Do not plough with an ox and a donkey together". To sow: (Deuteronomy 22:9) "Do not sow your vineyard [with two different species]". To harvest: (Deuteronomy 24:19) "When you reap your harvest [and forget a sheaf, leave it in the field for the poor". Kneading: (Numbers 15:20) "The first yield of your baking, [you shall set aside] a loaf [as a gift]". Slaughter: (Deuteronomy 18:3) "And give the priest the shoulder and the cheeks". A birds' nest: sending away the mother bird. Animals and birds: (Leviticus 17:13) "And slaughter, and cover the blood with dust". Seedlings: (Leviticus 19:23) "And you shall regard its fruit as forbidden". Graves of the dead: (Deuteronomy 14:1) "Do not gash yourselves". Shaving hair: (Leviticus 19:27) "Do not round off [the side-growth of your head]". Building a house: (Deuteronomy 22:8) "And write on the doorposts". Covering oneself with a shawl: "And you shall make for yourselves tzitzit". And you shall make -- make, and not from a thing already made. That you should not go out numbered and make from them, rather, the commandment is to bring white and techelet and make. When? When there is techelet, and now we do not have anything but white, since the techelet has been lost ("nignaz", lit. stored away, like in a geniza). (Numbers 15:38) "On the corners" -- and not in the middle, but on the corner. (ibid.) "A twisted thread" -- that one needs to twist them. Rabbi Meir says: what is the difference between techelet and all other colours? Techelet resembles the firmament, and the firmament resembles the Throne of Glory, as it says (Exodus 24:10) "And they saw the God of Israel... [under His feet there was a likeness of a pavement of sapphire...]". (Numbers 15:39) "And they shall be to you for tzitzit" -- that they shall be seen. And what is the measurement [of the tzitzit]? Beit Shammai says, four fingers, and Beit Hillel says three. And how many threads? Beit Shammai says four, and Beit Hillel says three. (ibid." "And you shall see them" -- this comes to exclude nightclothes -- or, this is nothing other than an exclusion of the blind. He responded and said, (Numbers 15:40) "That you should remember" -- it gives sight and it reminds. Reminder to one who cannot see, and sight to one who can see. "And you shall see it", "it" in the masculine and not in the feminine. That if you make it so, like it is the Throne of Glory, you will see it similar to the techelet... [trans. unfinished]

(6) EXCERPT......(B-Midbar 15;40) "So that you will remember and do all my mitzvot." This is comparable to one who was thrown into the sea. The captain extended a rope to him and said: 'Catch this rope in your hand and don't let it go, for if you let it go, you will have no life.' Even so, the Holy One (blessed be He) said to Israel: The whole time that you cleave to the mitzvot - (Dvarim 4:4) "And you who cleave to Ha-shem your God, you are all living today."  And similarly it says (Mishlei 4:13): "Hold tight to tradition/musar, don't let it alone, keep it safe, for it is your life."...

(Numb. 15:40, cont.:) AND THAT YOU MAY BE HOLY. When you perform the commandments, you are made holy, and fear of you <comes> over the nations. <If> you withdraw from the Torah, you become profaned. The Holy One said to Israel: In this world because of the evil drive, you withdraw from the commandments; in the age to come I am rooting it out of you. Thus it is stated (in Ezek. 36:26–27): THEN I WILL REMOVE THE HEART OF STONE FROM YOUR FLESH AND GIVE YOU A HEART OF FLESH, AND I WILL PUT MY SPIRIT WITHIN YOU. THEN I WILL MAKE YOU WALK IN MY STATUTES; AND YOU WILL OBSERVE MY ORDINANCES BY PERFORMING THEM.
