(12) And if you do obey these rules and observe them carefully, the ETERNAL your God will maintain faithfully for you the covenant made on oath with your fathers:

(1) BECAUSE. Ekev (because) has the same meaning as ekev (reward) in For ever, reward (Ps. 119:112). It means the reward which will be given at the end. The meaning of who keepeth covenant in the previous verse (v. 9) is that God kept the covenant with Abraham. If you will be among those that love Him, then He will continue to keep the covenant. If you will be among those who love Him, then He will love thee, and bless thee, and multiply thee (v. 13). This is the meaning of the covenant and the mercy (v. 12).

(1) AND IT SHALL COME TO PASS ‘EIKEV’ YE HEARKEN. Eikev means “because.” So also, ‘eikev’ (because) that Abraham hearkened to My voice. And Rashi wrote: “If you will hearken even to the lighter commandments which a person usually treads upon with his ‘heels’ [i.e., those commandments which a person is inclined to treat lightly] then G-d will keep His promise to you.” Now Scripture mentions the ordinances [And it shall come to pass ‘eikev’ ye hearken to these ‘ordinances’] perhaps because he admonishes them not to be disdainful of the lightly-esteemed ordinances such as the laws pertaining to monetary matters.
And the commentators have said that the meaning of the word eikev is that “in the end” there will be reward. Similarly, in keeping them [the ordinances of G-d] ‘eikev rav’ (there is [in the end] great reward). The verse here is thus stating: “and the end [the ultimate consequence] of your hearkening to the ordinances and your observing them is that G-d shall keep the covenant and the mercy, and He will love thee. ” This is correct, for in the Sacred Language the beginning of anything is called rosh [literally: “head”], as it is said, ‘rosh’ (the beginning of) Thy word is truth. So also is the leader of the generation called “the head of the people,” and the best of spices is called rosh. Similarly, the conclusion of any matter is called akeiv (heel) as the Sacred Language adopts these figurative expressions from the human body; and thus “the head” is the beginning while “the heel” is the conclusion and end of the body. Scripture also speaks of the head and the tail [with reference to people], figuratively using the body of the animal.
And Onkelos rendered the word eikev as chalaf (“in exchange for”), like ‘cheilef’ (in return for) your service. Onkelos thus made it an expression of “roundabout” [the end result of a series of events], derived from the verse, and ‘he’akov (the crooked) shall be made straight — that is, the circuitous road which goes roundabout [will become a straight, level path]. So also ‘akubah’ of blood means “it is surrounded and encircled” [with blood]. The verse here is thus stating [according to Onkelos]: “and it shall come to pass that the effect caused by your hearkening to the ordinances and your performing them will be that G-d will keep His covenant with you.” He has explained it well. A similar expression is ‘biglal’ (for the sake of) this thing which means “on account of,” from the word ‘v’gal’lu’ (and they roll) the stone. Similarly it is my opinion that every expression of akeivah is a term denoting “circle” or “circuit.” Thus: ‘akov haleiv’ (the heart is deceitful); ‘vaya’akveini’ (and he hath gotten the better of me) these two times;but Jehu did it ‘b’akbah’ (in subtlety) — all these being expressions of “rolling” and “circling.” Therefore they called Jacob “Jeshurun” [from the root yashar (straight and upright)] because the opposite of “the deceitful one” is he who is “upright” [as indicated by the name “Jeshurun”]. Similarly, the end-part of the foot, called akeiv — as it is said, and his hand seizing ‘ba’akeiv (the heel) of Esau — is so called because of its roundness, just as the [Sacred] Language calls the middle part [palm and sole] of the hand and foot kapoth, because of their being shaped like golden kapoth (spoons). This usage [of the term akeiv] is common in the [Sacred] Language, just as the Rabbis have said in the Sifre: “At His right hand was a fiery law unto them. When the word came forth from the mouth of the Holy One, blessed be He, it would go by way of the right hand of the Holy One to the left of Israel, v’okeiv (and it encircled) the camp of Israel twelve miles by twelve miles.” So also is the expression: “they come upon him ba’akifin,” meaning “with circuitous and subtle arguments,” like the word akeivin as these two letters [the veth and the fei] were considered by the Sages to be interchangeable, as I have already explained.
He mentioned these ordinances in order to warn exceedingly concerning the ordinances [i.e., judgments], for it is impossible that of a large nation, everyone be heedful of all commandments so as not to transgress any of them, and it is only through the judgments [of the court] that they establish [the firm authority of] the Torah, just as it says of them, and all Israel shall hear, and fear. Moreover, many people will have pity [and refrain from] stoning a man or burning him after the transgression had been committed, as it is said, Thine eye shall not pity him. Then also they might fear the mighty ones as well as those who lead astray, as it is said, ye shall not be afraid of the face of any man, for the judgment is G-d’s, and in the case of the false prophet it says, thou shalt not be afraid of him. He mentioned all these in the case of an inciter [to worship idols] saying, thou shalt not consent unto him, nor hearken unto him; neither shalt thine eye pity him, neither shalt thou spare, neither shalt thou conceal him, warning nor hearken unto him because of his misleading [you], neither shalt thine eye pity him because of the pity that compassionate people show towards the condemned, and neither shalt thou conceal him by remaining silent [and not presenting testimony against him] because of his might and fear of members of his family.

(1) והיה עקב תשמעון AND THE CONSEQUENCE WILL BE, IF YE HEARKEN (The Hebrew text may be taken to signify if you will hear the heel, עקב) — If, even the lighter commands which a person usually treads on with his heels (i.e. which a person is inclined to treat lightly), ye will hearken to,

(1) (Deut. 7:12:) “And it shall come to pass if (literally, in the heel of).” This text is related (to Ps. 49:6), “Why should I fear in the evil days, when the iniquity of my heels encompass me?” May the name of the Holy One, blessed be He, be blessed because He has given a Torah to Israel in which there are six hundred and thirteen commandments, some of which are light and some weighty. But because some of the commandments are light, people pay no attention to them. Instead they cast them under their heels [while] saying they are light. For that reason David was afraid of the Day of Judgment and said, “Master of the world, I am not afraid of the weighty commandments which are in the Torah, because they are weighty. Of what am I afraid? Of the light commandments, lest I have transgressed one of them, [not knowing] whether I have fulfilled it or not fulfilled it, because it is light; for you have said, ‘Be as mindful of the light commandments as of the weighty commandments.’” It therefore says (in Ps. 49:6), “Why should I fear in the evil days?” (Deut. 7:12:) “And it shall come to pass if (ekev) you heed [these statutes].” This text is related (to Ps. 19:11-12), “More delightful are they than gold, than much fine gold; [sweeter also than honey and the drippings of the comb]. Also by them is Your servant warned; [in keeping them there is great reward (ekev)]. Come and see how David glorified the words of Torah, where it is stated (ibid.), “More delightful are they than gold, than much fine gold.” And not only that, but among all the kinds of grains, none is more precious than pure semolina, which floats upon the [sieve] (zafah benapah); but the words of Torah are more precious than that, as stated (ibid., vs. 11), “sweeter also than honey and the drippings of the comb (nofet zufim).” R. Hanina said, “If you say that among all the beverages none is sweeter than honey, the words of Torah are [even] sweeter than honey.” David said to the Holy One, blessed be He, “Master of the universe, if You say that they (the commandments) of the Torah are sweet, Heaven forbid that I should have missed them. Rather (according to vs. 12), ‘Also by them is Your servant warned; in keeping them there is great reward,’” [meaning] the light commandments. Therefore it is written (in Ps. 31:20), “How abundant is the good which You have laid up [for those who fear You]….” This is the reward for the light commandments.

(15)I will put enmityBetween you and the woman,And between your offspring and hers;They shall strike at your head,And you shall strike at their heel.”

(15) I will put hostility between you and the woman, and between your offspring and her offspring. He shall strike you on the head, and you shall strike him on the heel. [He will remember you, what you did to him from the beginning, and you will expect him at the end].

(15) And I will put enmity between thee and the woman, and between the seed of thy son, and the seed of her sons; and it shall be when the sons of the woman keep the commandments of the law, they will be prepared to smite thee upon thy head; but when they forsake the commandments of the law, thou wilt be ready to wound them in their heel. Nevertheless for them there shall be a medicine, but for thee there will be no medicine; and they shall make a remedy for the heel in the days of the King Meshiha.

(15) And it shall be when the sons of the woman consider the law, and perform (its) instructions, they will be prepared to smite thee on thy head to kill thee; and when the sons of the woman forsake the commandment of the law, and perform not (its) instructions, thou wilt be ready to wound them in their heel, and hurt them. Nevertheless there shall be a medicine for the sons of the woman, but for thee, serpent, there shall be no medicine: but it is to be that for these there shall be a remedy for the heel in the days of the king Meshiha.

(52)how Your enemies, O ETERNAL One, have flung abuse,abuse at Your anointed at every step.

(1)the ends of Your anointed Heb. עקבות, the ends of the King Messiah. This is the language of the Mishnah (Sotah 49b): At the ends of the Messiah, audacity will increase; i.e., at the end of the exile, prior to the advent of the Messiah.

(15) The mishna lists more things that ceased: From the time when Rabbi Meir died, those who relate parables ceased; from the time when ben Azzai died, the diligent ceased; from the time when ben Zoma died, the exegetists ceased; from the time when Rabbi Yehoshua died, goodness ceased from the world; from the time when Rabban Shimon ben Gamaliel died, locusts come and troubles multiplied; from the time when Rabbi Elazar ben Azarya died, the sages ceased to be wealthy; from the time when Rabbi Akiva died, the honor of the Torah ceased; from the time when Rabbi Ḥanina ben Dosa died, the men of wondrous action ceased; from the time when Rabbi Yosei the Small died, the pious were no more. And why was he called the Small? Because he was the smallest of the pious, meaning he was one of the least important of the pious men. From the time when Rabban Yoḥanan ben Zakkai died, the glory of wisdom ceased; from the time when Rabban Gamliel the Elder died, the honor of the Torah ceased, and purity and asceticism died. From the time when Rabbi Yishmael ben Pavi died, the glory of the priesthood ceased; from the time when Rabbi Yehuda HaNasi died, humility and fear of sin ceased. Rabbi Pineḥas ben Ya’ir says: From the time when the Second Temple was destroyed, the ḥaverim and free men of noble lineage were ashamed, and their heads were covered in shame, and men of action dwindled, and violent and smooth-talking men gained the upper hand, and none seek, and none ask, and none inquire of the fear of Heaven. Upon whom is there for us to rely? Only upon our Father in Heaven. Rabbi Eliezer the Great says: From the day the Second Temple was destroyed, the generations have deteriorated: Scholars have begun to become like scribes that teach children, and scribes have become like beadles, and beadles have become like ignoramuses, and ignoramuses are increasingly diminished, and none ask and none seek. Upon whom is there to rely? Only upon our Father in Heaven. He also said: In the times of the approach of the Messiah, impudence will increase and high costs will pile up. Although the vine shall bring forth its fruit, wine will nevertheless be expensive. And the monarchy shall turn to heresy, and there will be no one to give reproof about this. The meeting place of the Sages will become a place of promiscuity, and the Galilee shall be destroyed, and the Gavlan will be desolate, and the men of the border shall go round from city to city to seek charity, but they will find no mercy. And the wisdom of scribes will putrefy, and people who fear sin will be held in disgust, and the truth will be absent. The youth will shame the face of elders, elders will stand before minors. Normal family relations will be ruined: A son will disgrace a father; a daughter will rise up against her mother, a daughter-in-law against her mother-in-law. A man’s enemies will be the members of his household. The face of the generation will be like the face of a dog; a son will no longer be ashamed before his father. And upon what is there for us to rely? Only upon our Father in heaven. Rabbi Pineḥas ben Ya’ir says: Torah study leads to care in the performance of mitzvot. Care in the performance of mitzvot leads to diligence in their observance. Diligence leads to cleanliness of the soul. Cleanliness of the soul leads to abstention from all evil. Abstention from evil leads to purity and the elimination of all base desires. Purity leads to piety. Piety leads to humility. Humility leads to fear of sin. Fear of sin leads to holiness. Holiness leads to the Divine Spirit. The Divine Spirit leads to the resurrection of the dead.
