1. And Adam knew his wife Eve. Moses now begins to describe the propagation of mankind; in which history it is important to notice that this benediction of God, “Increase and multiply,” was not abolished by sin; and not only so, but that the heart of Adam was divinely confirmed so that he did not…

2. And she again bare his brother Abel It is well known whence the name of Cain is deduced, and for what reason it was given to him. For his mother said, קניתי (kaniti) I have gotten a man; and therefore she called his name Cain. The same explanation is not given with respect to Abel.

4. And the Lord had respect unto Abel , etc. God is said to have respect unto the man to whom he vouchsafes his favor. We must, however, notice the order here observed by Moses; for he does not simply state that the worship which Abel had paid was pleasing to God, but he begins with the person of…

5. But unto Cain and to his offering he had not respect. It is not to be doubted, that Cain conducted himself as hypocrites are accustomed to do; namely, that he wished to appease God, as one discharging a debt, by external sacrifices, without the least intention of dedicating himself to God.

6. And the Lord said unto Cain. God now proceeds against Cain himself, and cites him to His tribunal, that the wretched man may understand that his rage can profit him nothing. He wishes honor to be given him for his sacrifices; but because he does not obtain it, he is furiously angry.

7. If thou does well. In these words God reproves Cain for having been unjustly angry, inasmuch as the blame of the whole evil lay with himself. For foolish indeed was his complaint and indignation at the rejection of sacrifices, the defects of which he had taken no care to amend.

8. And Cain talked with Abel his brother. Some understand this conversation to have been general; as if Cain, perfidiously dissembling his anger, spoke in a fraternal manner.

9. Where is Abel ? They who suppose that the father made this inquiry of Cain respecting his son Abel, enervate the whole force of the instruction which Moses here intended to deliver; namely, that God, both by secret inspiration, and by some extraordinary method, cited the parricide to his…

10. What hast thou done ? The voice of thy brother’s blood Moses shows that Cain gained nothing by his tergiversation. God first inquired where his brother was; he now more closely urges him, in order to extort an unwilling confession of his guilt; for in no racks or tortures of any kind is there…

11. And now art thou cursed from the earth. Cain, having been convicted of the crime, judgment is now pronounced against him. And first, God constitutes the earth the minister of his vengeance, as having been polluted by the impious and horrible parricide: as if he had said, ‘Thou didst just now…

12. When thou tillest the ground. This verse is the exposition of the former; for it expresses more clearly what is meant by being cursed from the earth, namely, that the earth defrauds its cultivators of the fruit of their toil.

13. My punishment is greater , etc. Nearly all commentators agree that this is the language of desperation; because Cain, confounded by the judgment of God, had no remaining hope of pardon.

14. Every one that findeth me. Since he is no longer covered by the protection of God, he concludes that he shall be exposed to injury and violence from all men. And he reasons justly; for the hand of God alone marvelously preserves us amid so many dangers.

15. Therefore , whosoever slayeth Cain. They who think that it was Cain’s wish to perish immediately by one death, in order that he might not be agitated by continual dangers, and that the prolongation of his life was granted him only as a punishment, have no reason, that I can see, for thus…

16. And Cain went out from the presence of the Lord. Cain is said to have departed from the presence of God, because, whereas he had hitherto lived in the earth as in an abode belonging to God, now, like an exile removed far from God’s sight, he wanders beyond the limits of His protection.

17. And Cain knew his wife. From the context we may gather that Cain, before he slew his brother, had married a wife; otherwise Moses would now have related something respecting his marriage; because it would be a fact worthy to be recorded, that any one of his sisters could be found, who would not…

19. And Lamech took unto him two wives. We have here the origin of polygamy in a perverse and degenerate race; and the first author of it, a cruel man, destitute of all humanity.

20. Jabal ; he was the father of such as dwell in tents. Moses now relates that, with the evils which proceeded from the family of Cain, some good had been blended.

23. Hear my voice , ye wives of Lamech. The intention of Moses is to describe the ferocity of this man, who was, however, the fifth in descent from the fratricide Cain, in order to teach us, that, so far from being terrified by the example of divine judgment which he had seen in his ancestor, he…

24. Cain shall be avenged sevenfold. It is not my intention to relate the ravings or the dreams of every writer, nor would I have the reader to expect this from me; here and there I allude to them, though sparingly, especially if there be any color of deception; that readers, being often…

25. Adam knew his wife again. Some hence infer that our first parents were entirely deprived of their offspring when one of their sons had been slain, and the other was cast far away into banishment.

26. Then began men to call upon the name of the Lord. In the verb ‘to call upon,’ there is a synecdochee, for it embraces generally the whole worship of God. But religion is here properly designated by that which forms its principal part.
