(1) והאדם ידע AND THE MAN KNEW already before the events related above took place — before he sinned and was driven out of the Garden of Eden. So, also, the conception and birth of Cain took place before this. Had it been written, וידע אדם it would imply that after he was driven out children were born to him (Genesis Rabbah 22:2).

קין — She called him so with reference to her use of the word.

ה‘ — ;את קניתי is like ‘עם ה “with the Lord”; she meant to say: when He created me and my husband He created us by Himself, but in the case of this one we are copartners with Him (cf. Niddah 31a).

את קין… את אחיו את הבל —The threefold ‘את’ signify extension of the scope of the text, teaching that a twin sister was born with Cain, and that with Abel two were born; consequently the text states ותוסף “and she bore more’’ than the previous time (Genesis Rabbah 22:3).

רעה צאן A FEEDER OF FLOCKS — Because the earth had been cursed he refrained from cultivating it.

מפרי האדמה OF THE FRUIT OF THE GROUND —of the worst fruits (Genesis Rabbah 22:5); there is an Agada which says that it was linseed (Midrash Tanchuma, Bereshit 9).

וישע AND HE HAD REGARD— and He turned to; similarly in the next verse “He had no respect for his offering” means, “He did not turn to it.” Similarly, (Isaiah 17:8) ולא ישעה אל המזבחות which means “And he shall not turn towards the altars”; so also (Job 14:6) שעה מעליו “turn away from him” — disregard him.

וישע AND HE HAD REGARD — Fire descended from heaven and consumed his offering.

הלא אם תטיב IF THOU MENDEST — Its meaning is as the Targum gives it: “if thou wilt improve thy doings, thou shalt be forgiven”.

לפתח חטאת רובץ SIN CROUCHETH AT THE ENTRANCE — Right up to the door of your grave (until your death) your sin will be preserved.

ואליך תשוקתו AND UNTO THEE IS ITS LONGING — The longing of sin; it refers to the evil inclination. This is continually longing and desiring to make you sin.

ואתה תמשול בו NEVERTHELESS THOU MAYEST RULE OVER IT — If you desire to, you can gain the victory over it (Kiddushin 30b).

ויאמר קין אל הבל AND CAIN SPAKE TO ABEL — He began an argument, striving and contending with him, to seek a pretext to kill him. There are Midrashic explanations of these words, but this is the plain sense of the text.

איה הבל אחיך WHERE IS ABEL THY BROTHER — thus entering into a friendly conversation with him: perhaps he might repent and say, “I have killed him, and sinned against You” (Genesis Rabbah 19:11).

לא ידעתי I KNOW NOT — He became a deceiver of the Most High (i. e. he persuaded himself that he could deceive Him) (Numbers Rabbah 20:6).

השומר אחי אנכי AM I MY BROTHER’S KEEPER — This is a question. Similarly, wherever ‘ה has a חטף פתח it introduces a question.

דמי אחיך THY BROTHERS BLOOD — דמי is plural — bloods” — his blood and the blood of his possible descendants (Genesis Rabbah 22:9). Another explanation of why the plural is used: he inflicted upon him many wounds, because he knew not whence his soul would depart (i. e. which blow would prove fatal) (Sanhedrin 37b).

ארור אתה מן האדמה CURSED BE THOU FROM THE GROUND or, MORE THAN THE GROUND — More than the ground has already been cursed on account of its sin (cf. Rashi on Genesis 1:11): in this, too, it has again sinned

אשר פצתה את פיה לקחת את דמי אחיך IN THAT IT HATH OPENED ITS MOUTH TO TAKE THY BROTHER’S BLOOD: therefore do I impose upon it an additional curse regarding you—“it shall not henceforth yield unto thee its strength”.

נע ונד A VAGABOND AND A WANDERER — You shall not be permitted to dwell in one place.

גדול עוני מנשוא MY PUNISHMENT IS GREATER THAN I CAN BEAR (literally, my sin is greater than what can be borne) — This is a question: You bear the worlds above and below. and is it impossible for You to bear my sin? (Genesis Rabbah 22:11).

לכן כל הרג קין VERILY, WHOSOEVER SLAYETH CAIN — This is one of the verses where the construction is elliptical (literally, which abbreviate their statements), which give only a suggestion and do not fully explain. “Verily, whosoever slayeth Cain” express a threat, suggesting the consequence — “thus shall be done to him”, “thus and thus shall be his punishment”, without explicitly explaining what the punishment would be.

שבעתים יקם VENGEANCE SHALL BE TAKEN SEVENFOLD — God says, I do not wish to take vengeance on Cain now, but at the end of seven generations I will execute my vengeance upon him, that Lamech, one of his descendants, will arise and slay him. The end of this verse which states, “vengeance shall be taken in the seventh generation” — which is the vengeance taken on Cain for Abel — teaches us that the first part of the verse is a threat made in order that no creature might injure him. A similar elliptical expression is the following: (2 Samuel 5:8) “And David said, whosoever smiteth the Jebusites and getteth up to the gutter” — but it does not explicitly state what would be done to that person. Scripture, however, here speaks by a suggestion only, meaning, whosoever smiteth the Jebusites and getteth up to the gutter and approacheth the gate and conquereth it and the blind etc. … slaying also them (the blind and the lame) because they said, “there are the blind and the lame: David cannot come into the house” — he who smiteth these, I shall make him chief and captain. Here (in the Book of Samuel) it abridges the narrative, but in Chronicles (1 Chronicles 11:6) it explicitly states, “he shall become chief and captain.”

וישם ה' לקין אות AND THE LORD SET A SIGN FOR CAIN — He inscribed on his forehead a letter of His Divine Name (Pirkei DeRabbi Eliezer 21). Other editions of Rashi add the following: another interpretation of “Whoever will find me will slay me”: this refers to cattle and beasts, since there were then no human beings in the world of whom he might be afraid except his father and mother, and, of course, he did not fear that they would slay him. He, therefore, said, “Until now the fear of me was upon all animals — as it is written”, (Genesis 9:2) “And the fear of you shall be upon all beasts of the field” etc. — now, however, because of my sin the animals will no longer fear me and will kill me. God immediately set a sign for Cain, viz., he again made the animals be in fear of him.

ויצא קין AND CAIN WENT AWAY — He went away in pretended humility as though he would deceive the Most High (Genesis Rabbah 22:13).

בארץ נוד IN THE LAND OF NOD — In the land where all exiles wander about.

קדמת עדן ON THE EAST OF EDEN — Thereto his father went into exile when he was driven out from the Garden of Eden. as it is said, (3:24) “And He placed in the east of the Garden of Eden” a watch on the road that leads to the entrance of the Garden, from which one may infer that Adam was there (in the East) (Genesis Rabbah 21:9). Indeed, we find, also, that the Eastern quarter always forms a place of refuge for murderers, as it is said, (Deuteronomy 4:41) “Then Moses set aside three cities of refuge towards the place of sun-rise [that a murderer might flee thither].” Another explanation of בארץ נוד IN THE LAND OF NOD — (taking נוד in the sense of “movement”) — wherever he went the earth quaked beneath him, and people said, “Turn away from him: this is the man who killed his brother” (Midrash Tanchuma, Bereshit 9).

ויהי AND HE WAS— Cain was, not Enoch — בונה עיר BUILDING A CITY ויקרא שם העיר AND HE CALLED THE NAME OF THE CITY (named the city) as a memorial of his son — חנוך.

.חנוך AND IRAD BEGET — There are passages where it says of the male הוליד, and there are places where it says ילד, because this root ילד is used in two senses: in reference to a woman giving birth to a child through the agency of a male old French naitre; English to give birth to and the act of begetting by a man old French engendrer; English engender, beget. When it says הוליד, [in the Hiphil form] it speaks of the man in his relation to the act of giving birth by the woman — this or that man caused his wife to give birth to a son or daughter; when it says ילד it refers to the act of begetting by the man himself.

ויקח לו למך AND LAMECH TOOK UNTO HIMSELF — It would not have been necessary to state all this in detail except to inform us by the conclusion of the narrative that the Holy One, blessed be He, kept the promise He made when He said, שבעתים יקם קין “vengeance shall be taken of Cain after seven generations״; for Lamech arose after he had begotten children and had raised the seventh generation and killed Cain. It is to this that the statement refers: כי איש הרגתי לפצעי וגו “for I have slain a man to my wounding etc.” (v. 23).

שתי נשים TWO WIVES — This was the custom of the generation that lived before the time of the Flood; they had two wives, one for child-bearing, the other for frivolous companionship and charm; the latter was given a cup of some drug to drink in order that she might become barren, and was dressed up like a bride and fed with the best food, whilst her fellow-wife was left without her husband’s companionship and ever mourned like a widow. Job expressly mentions this (Job 24:21). “He is a companion to (or, he feedeth) the barren that beareth not, and does not good to the widow”, as it is explained in the Agada of Pereq Chelek (see also Genesis Rabbah 23:2).

עדה ADAH — She was the wife intended for propagation, and she was so named because she was repulsive to him and was kept aloof from him [other versions read “from his table “] for עדה is the Aramaic word for סורה kept aloof.”

צלה ZILLAH — She was the one for companionship alone, and she was so named because she always abided in his shadow (צל means “shadow”). Thus is the statement of the Agada in Genesis Rabbah 23:2).

אבי יושב אהל ומקנה THE FATHER OF SUCH AS ABIDE IN TENTS AND OF SUCH THAT HAVE CATTLE — He was the first of those who pastured cattle, and he dwelt in tents, a month here and a month there, on account of the pasture necessary for his sheep; for when the grass was finished in one place he went away and pitched his tent in another place. There is a Midrashic statement (Genesis Rabbah 23:3) that he built temples for idol worship, (for ומקנה may be read ומקנה –– provoking jealousy), just as you say, (Ezekiel 8:3) "the image of jealousy which provoketh God to jealousy" (המקנה); similarly his brother handled the harp and guitar to make music for idol worship.

תובל קין TUBAL-CAIN — He refined Cain’s handicraft. The word תובל is connected in meaning with תבלין (spices which give a refined and improved taste to food); he refined and improved the work of Cain by providing weapons for murderers (Genesis Rabbah 23:3).

לטש כל חרש נחשת וברזל THE FORGER OF EVERY CUTTING INSTRUMENT OF BRASS AND IRON — He sharpened tools used in brass and iron work; לוטש has the some meaning as (Job 16:9) ילטוש “He sharpeneth his eye upon me.” The word חרש is not of the form פעל (a noun like אֹכֶל, אֹהֶל etc.), but of the form פועל (a participle), for it has the vowel קמץ קטן (what we term צירה) and its accent is on the last syllabic (whereas the noun form has the accent on the first syllable, and the second has a Segol, like קדש), and the meaning is that he sharpened and polished all cutting implements (כל חרש) used in work of brass and iron.

נעמה NAAMAH — She was Noah’s wife (Genesis Rabbah 23:3).

שמען קולי HEAR MY VOICE — For his wives separated from him because he had killed Cain and Tubal-Cain, his own son. Lamech was blind and Tubal-Cain used to lead him. The latter saw Cain and thought him to be an animal. He therefore told his father to draw the bow, and thus Lamech killed him. As soon as he learned that it was his forefather Cain, he smote his hands together, struck his son between them and so killed him too. His wives thereupon separated from him, and he endeavoured to appease them,

saying שמען קולי “Hear my voice”— obey me and return to me: for the man I slew — was he slain by my wounding? i. e. did I wound him with premeditation, that the wound should be called by my name (i. e. attributed to me); and the child that I slew — was it slain by my blow? (i. e. by a blow directed intentionally by me?) [Rashi here inserts the word בתמיה which he uses frequently to direct that the preceding words should be read as a question.] Did I not act inadvertently and not with premeditation? This was not my wound, nor was this my blow!

פצע wound, is the stroke inflicted by a sword or arrow (old French macheure).

כי שבעתים יקם קין IF CAIN SHALL BE AVENGED SEVENFOLD — (according to Rashi, as previously explained, it signifies “If vengeance shall be taken on Cain after seven generations”). If in the case of Cain who killed with premeditation the punishment was suspended for him until the seventh generation, in the case of myself who slew inadvertently does it not necessarily follow that it should be suspended for me until many seven generations?

שבעים ושבעה SEVENTY AND SEVEN — He uses a term that denotes many periods of seven generations. Thus did R. Tanchuma 1:1:11 explain this passage; but the Midrash Rabbah (Genesis Rabbah 23:4) does not mention that Lamech slew anyone at all, and only states that his wives had lived apart from him after they had born children, because God’s decree had been issued that Cain’s descendants should be exterminated after seven generations. They said, “Why should we bear children only to be destroyed? Soon the Flood will come and will sweep everyone away!” Lamech then said unto them, “Did ‘I’ slay a man ‘לפצע for my wounding” (i.e. that I should be wounded — punished)? Did “I” slay Abel who was a man in height but a child in years, that my descendants should be exterminated on account of this sin (the sin of Cain who killed Abel)? If Cain who did kill had his punishment suspended until the seventh generation, I who have not killed — does it not necessarily follow that my punishment) should be suspended for many seven generations? This, however, is an absurd argument a fortiori, for if so, the Holy One, blessed be He, could never exact his debt nor fulfil his word.

וידע אדם AND ADAM KNEW — Lamech came to Adam Harishon, complaining about his wives. He (Adam) said to them: “Is it for you to be overparticular regarding God’s decrees? You do your duty, and He will do His!” They replied to him: “First correct yourself: have you not lived apart from your wife these 130 years, ever since, through you, death was decreed as a punishment?” At once ‘וידע אדם עוד וגו “Adam knew his wife עוד ” — What signifies the word עוד? It is used here to teach that his love for her was now greater than before (Genesis Rabbah 23:4-5).

אז הוחל THEN IT WAS BEGUN [TO CALL etc.] — The word הוחל must be connected in meaning with חולין “profane matters “) viz, calling the names of men and the names of idols after the name of the Holy One, blessed be He — making them the objects of idolatrous worship and calling them Deities (Genesis Rabbah 23:7).
