Midrash su Deuteronomio 28:10

R. Abin b. R. Ada, in the name of R. Isaac, said: "Whence do we learn that the Holy One, praised be He! lays Tephilin? It is said (Is. 62, 8.) Sworn hath the Lord by His right hand and by the arm of His strength. By His right hand, is meant the Torah, for it is said (Deu. 33, 2.) From His right hand, He gave a fiery law unto them; and by His strength, is meant Tephilin; as it is said (Ps. 29, 11.) The Lord will give strength unto His people. How do we know that the Tephilin are a strength to Israel? It is said (Deu. 28, 10.) And all the nations of the earth shall see, that Thou art called by the name of the Lord, and they shall be afraid of Thee; and we are also taught that R. Eliezer, the Great, says 'This (the above verse) means the Tephilin of the head.'' R. Nachman b. Isaac said to R. Chiya b. Abin: "What is written in the Tephilin of the Sovereign of the universe?" "It is written," he answered, "Who is like thy people Israel, the only nation." (I Chr. 17, 21.) "And does the Holy One, praised be He! praise himself with the glory of Israel?" "Yea, for it is written (Deu. 26, 17.) Thou hast this day acknowledged the Lord, etc., and the Lord hath acknowledged thee, this day, i.e., the Holy One, praised be He! said unto Israel 'You have made me the only object of love in the world — as it is written (Deu. 6, 4.) Hear, O Israel, the Lord our God, is one God; I will therefore make you the only object of love in the world — as it is written (I Chr. 17, 21.) And who is like thy people, Israel the only nation'" R. Acha, the son of Raba, said to R. Ashi: "You may be right concerning one section of the Tephilin, what about the remaining sections?" "In the remaining sections," [said R. Ashi] "are. For what great nation is there (Deu. 4, 7); And what great nation (Ib. ib.); Happy art thou, O Israel! (Ib. 33, 29); Or hath a God essayed, (Ib. 4, 34.) So that he may set thee, the highest (Ib. 26, 19)." "If so then there are more than four sections?" "But," [said he], "Or what great nation is there. And what great nation, both being practically [in meaning] alike, are one section; Happy art thou Israel, and For what part of a nation, are another section; Or hath a God essayed, is the third section; and So that He may set thee the highest, is the fourth section; and all these verses are written and [put together into one section which is] placed also in the Tephilin of the hand.

Raba expounded: "As a reward to Abraham who said (Ib., ib., ib.) Although I am but dust and ashes, his children merited the following two commandments, the rule of the Parah A'dumah and the ashes of a Sota." But there is also the ashes that are used for covering the blood [of a beast and fowl]. The ashes used for covering the blood is only the prologue to a commandment but not the commandment itself. Raba expounded: "As a reward for what Abraham said, (Ib. 14, 23) And that I will not take from a, thread, even to a shoe-lachet, his children merited the following two commandments, the straps of the Tephillin and the T'cheileth of the Tzitzith It is readily understood that the strap of the Tephillin is a reward, for it is written (Dept. 28, 10) And all the nations of the world shall see, that thou art called by the name of the Lord, and they shall be afraid of thee. And we are taught that R. Elazar the Great says: "This refers to the Tephillin of the head." But as to the thread of Tcheleth, what kind of a reward is this? This is as R. Maier said in the following Baraitha, "Why was the color blue chosen from all other colors? Because blue resembles the sea, the sea resembles the heaven, and the heaven resembles the Divine Throne, as it is said (Ex. 24, 10) They saw the God of Israel; and the place under His feet was like a paved work of brilliant sapphire, and like the color of heaven in clearness. And again it is written (Ez. 1, 26) There was like the appearance of a sapphire stone, the likeness of a throne."

(Fol. 53b) (Deut. 28, 10) And all the peoples of the earth shall see that the name of the Lord is called upon thee and they shall be afraid of thee. We are taught that R. Eliezer the great says: "This refers to the Tephilin (phylacteries) of the head." Said R. Chana b. Bizna in the name of R. Simon the pious: "Infer from this that the Holy One, praised be He! showed unto Moses the knot of the Tephilin."
