And Cain said to his brother, Let us go out to the field. And when they were in the field, Cain rose up against Abel his brother and killed him.
And the Lord said to Cain, Where is Abel your brother? And he said, I do not know. Am I my brother’s keeper? And [the Lord] said, What have you done? The voice of your brother’s blood is crying to Me from the ground.
And now you are cursed by reason of the earth, which has opened its mouth to receive your brother’s [shed] blood from your hand. When you till the ground, it shall no longer yield to you its strength; you shall be a fugitive and a vagabond on the earth [in perpetual exile, a degraded outcast]. Then Cain said to the Lord, My punishment is [c]greater than I can bear.
Behold, You have driven me out this day from the face of the land, and from Your face I will be hidden; and I will be a fugitive and a vagabond and a wanderer on the earth, and whoever finds me will kill me. And the Lord said to him, Therefore, if anyone kills Cain, vengeance shall be taken on him sevenfold. And the Lord set a mark or sign upon Cain, lest anyone finding him should kill him.
Genesis 4 : 8 – 15 (Amplified Bible)
“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.”#
