41 Now Adam knew Eve his wife, and she conceived and bore Cain, and said, "I have acquired a man from the Lord." 2 Then she bore again, this time his brother Abel. Now Abel was a keeper of sheep, but Cain was a tiller of the ground.
3 And in the process of time it came to pass that Cain brought an offering of the fruit of the ground to the Lord. 4 Abel also brought of the firstborn of his flock and of their fat. And the Lord respected Abel and his offering, 5 but He did not respect Cain and his offering. And Cain was very angry, and his countenance fell.
6 So the Lord said to Cain, "Why are you angry? And why has your countenance fallen? 7 If you do well, will you not be accepted? And if you do not do well, sin lies at the door. And its desire is for you, but you should rule over it."
8 Now Cain talked with Abel his brother; and it came to pass, when they were in the field, that Cain rose up against Abel his brother and killed him.
9 Then the Lord said to Cain, "Where is Abel your brother?" He said, "I do not know. Am I my brother's keeper?" 10 And He said, "What have you done? The voice of your brother's blood cries out to Me from the ground. 11 So now you are cursed from the earth, which has opened its mouth to receive your brother's blood from your hand. 12 When you till the ground, it shall no longer yield its strength to you. A fugitive and a vagabond you shall be on the earth."
13 And Cain said to the Lord, "My punishment is greater than I can bear! 14 Surely You have driven me out this day from the face of the ground; I shall be hidden from Your face; I shall be a fugitive and a vagabond on the earth, and it will happen that anyone who finds me will kill me." 15 And the Lord said to him, "Therefore, whoever kills Cain, vengeance shall be taken on him sevenfold." And the Lord set a mark on Cain, lest anyone finding him should kill him.
16 Then Cain went out from the presence of the Lord and dwelt in the land of Nod on the east of Eden.

Commentary on Genesis 4:1-7
(Read Genesis 4:1-7)
When Cain was born, Eve said, I have gotten a man from the Lord. Perhaps she thought that this was the promised seed. If so, she was wofully disappointed. Abel signifies vanity: when she thought she had the promised seed in Cain, whose name signifies possession, she was so taken up with him that another son was as vanity to her. Observe, each son had a calling. It is the will of God for every one to have something to do in this world. Parents ought to bring up their children to work. Give them a Bible and a calling, said good Mr. Dod, and God be with them. We may believe that God commanded Adam, after the fall, to shed the blood of innocent animals, and after their death to burn part or the whole of their bodies by fire. Thus that punishment which sinners deserve, even the death of the body, and the wrath of God, of which fire is a well-known emblem, and also the sufferings of Christ, were prefigured. Observe that the religious worship of God is no new invention. It was from the beginning; it is the good old way, Revelation 3:20. And those well deserve to perish in their sins, that will not go to the door to ask for the benefit of this sin-offering. God's acceptance of Abel's offering did not change the birthright, and make it his; why then should Cain be so angry? Sinful heats and disquiets vanish before a strict and fair inquiry into the cause.
Commentary on Genesis 4:8-15
(Read Genesis 4:8-15)
Malice in the heart ends in murder by the hands. Cain slew Abel, his own brother, his own mother's son, whom he ought to have loved; his younger brother, whom he ought to have protected; a good brother, who had never done him any wrong. What fatal effects were these of our first parents' sin, and how must their hearts have been filled with anguish! Observe the pride, unbelief, and impenitence of Cain. He denies the crime, as if he could conceal it from God. He tries to cover a deliberate murder with a deliberate lie. Murder is a crying sin. Blood calls for blood, the blood of the murdered for the blood of the murderer. Who knows the extent and weight of a Divine curse, how far it reaches, how deep it pierces? Only in Christ are believers saved from it, and inherit the blessing. Cain was cursed from the earth. He found his punishment there where he chose his portion, and set his heart. Every creature is to us what God makes it, a comfort or a cross, a blessing or a curse. The wickedness of the wicked brings a curse upon all they do, and all they have. Cain complains not of his sin, but of his punishment. It shows great hardness of heart to be more concerned about our sufferings than our sins. God has wise and holy ends in prolonging the lives even of very wicked men. It is in vain to inquire what was the mark set upon Cain. It was doubtless known, both as a brand of infamy on Cain, and a token from God that they should not kill him. Abel, being dead, yet speaketh. He tells the heinous guilt of murder, and warns us to stifle the first risings of wrath, and teaches us that persecution must be expected by the righteous. Also, that there is a future state, and an eternal recompence to be enjoyed, through faith in Christ and his atoning sacrifice. And he tells us the excellency of faith in the atoning sacrifice and blood of the Lamb of God. Cain slew his brother, because his own works were evil, and his brother's righteous, 1 John 3:12. In consequence of the enmity put between the Seed of the woman and the seed of the serpent, the war broke out, which has been waged ever since. In this war we are all concerned, none are neuter; our Captain has declared, He that is not with me is against me. Let us decidedly, yet in meekness, support the cause of truth and righteousness against Satan.
Commentary on Genesis 4:16-18
(Read Genesis 4:16-18)
Cain cast off all fear of God, and attended no more on God's ordinances. Hypocritical professors, who dissemble and trifle with God, are justly left to themselves to do something grossly scandalous. So they throw off that form of godliness to which they have been a reproach, and of which they deny the power. Cain went out from the presence of the Lord, and we never find that he came into it again, to his comfort. The land Cain dwelt in was called the land of Nod, which means, 'shaking,' or 'trembling,' and so shows the restlessness and uneasiness of his own spirit, or 'the land of a vagabond:' they that depart from God cannot find rest any where else. Those on earth who looked for the heavenly city, chose to dwell in tabernacles or tents; but Cain, as not minding that city, built one on earth. Thus all who are cursed of God seek their settlement and satisfaction here below.
