Midrash su Deuteronomio 20:8

Another explanation of the word va-yarek: This indicates that he thinned out (herikan) their numbers by saying to them: What man is there that is fearful and fainthearted? (Deut. 20:8). That is, whosoever is fearful because of his sins and weak (ve-rakh) of heart (fainthearted) on account of his evil deeds, let him return home, lest his heart melt away (ibid.). With this statement, he thinned out their ranks one by one until only Eliezer remained. Whence do we know this? We know it from the numeral value of the letters of Eliezer’s name. The alef is one, the lamed, thirty, the yod, ten, the ayin seventy, the zayin, seven, and the resh, two hundred, totaling three hundred and eighteen in all (and Scripture states that He led forth … three hundred and eighteen) (Gen. 14:14). And yet that is followed by the singular form he pursued, rather than the plural “they pursued” (implying only one).

How do we know that the passages are to be on one roll of parchment? We can deduce this from the fact that it is written: And it shall be for a sign unto thee (Exod. 13:9)—for thee, and not (just) for others.²⁴Just as it appears on one container to other, so it should be one parchment for you. What is the size of the phylactery strip? R. Rami the son of Abba stated that R. Simeon the son of Lakish said: It is the size of the snapping finger. Which is the snapping finger? The middle finger. And its width is that of the thickness of barley corn. The law enjoins one to put the hand phylactery on first, and then pronounce the blessing: “Our God, who sanctifies us by His commandments and has commanded us to put on the phylacteries.” After that one dons the head phylactery while offering the blessing: “Our God, King of the Universe, who sanctifies us and has commanded us concerning the law of the phylacteries.” However, if he speaks in between the hand phylactery and the head phylactery, he is guilty of a transgression for which he must return home from the battlefront.²⁵As laid down in Deut. 20:8, according to the rabbis; one who has a transgression on his conscience should not remain on the battlefield of a war of conquest, aside from Joshua’s wars. This transgression is considered serious enough to fall in that category. But if he pauses while putting on the hand or head phylactery with the phrase “His great name” or to recite the Kedushah,²⁶A prayer in the ritual; “Holy, holy, holy is the Lord of Hosts.” he need not return from the battle. He must start over again, for each phylactery requires two blessings.²⁷One for itself and one for its companion phylactery. If recited together they support each other. However, if one should interrupt the blessings of the phylacteries in order to respond with the words “His great name” or the Kedushah, he has canceled the first blessing and must recite both of them again. Surely it is not necessary to state that if he discusses secular matters during that time, he is guilty of a serious transgression. When he takes off the phylacteries he must remove the head phylactery first and then the hand phylactery.
