Commentary
12 notes on this verseTo what a shameful pitch of presumptuous impudence had Cain arrived when he could thus insult the Lord God! If it had not been on record in the pages of Inspiration, we might almost have doubted whether a man could speak so impudently when actually conscious that God Himself was addressing Him. Men blaspheme frightfully, but it is usually because they forget God and ignore His Presence. But Cain was conscious that God was speaking to him. He heard Him say, "Where is Abel your brother?"

Where is your brother Abel
on Genesis 4:9-10
God asks Cain where his brother Abel is, as He asked Adam where he was one chapter earlier. Henry notes that the Hebrew reads bloods, in the plural. The voice of Abel's blood cries from the ground, and Hebrews 12:24 says the blood of Jesus speaks a better word.

(69) Why he who had slain his brother makes answer as if he were replying to a man; and says, "I do not know: am I my brother's keeper?" (#Ge 4:9). It is the opinion of an atheist to think that the eye of God …
God appeared to Cain with kindness, so that if he repented, the sin of murder that his fingers had committed might be effaced by the compunction on his lips.
But Cain was filled with wrath instead of compunction. To him who knows all, who asked him about his brother in order to win him back, Cain retorted angrily and said, "I do not know, am I my brother's keeper?"
Cain was at once the most wicked and foolish of men in believing that for committing the greatest of crimes it would be sufficient if he avoided other human witnesses. In fact God was the primary witness to his fratricide.
The divine Scripture always cries out and speaks; hence God also says to Cain, "The voice of your brother's blood cries out to me."

And the Lord said to Cain: Where is Abel your brother? Not as if ignorant, to learn from him, but as a judge questioning a defendant whom he will punish.
He answered: I do not know. Am I my brother's keeper? A foolish and equally arrogant answer; foolish, since he thought he could deceive Him who knew his sinful conscience and accused him of the crime of fratricide even before it was committed, as the …

To what a shameful pitch of presumptuous impudence had Cain arrived when he could thus insult the Lord God! If it had not been on record in the pages of Inspiration, we might almost have doubted whether a man could speak so impudently when actually conscious that God Himself was addressing Him. Men blaspheme frightfully, but it is usually because they forget God and ignore His Presence. But Cain was conscious that God was speaking to him. He heard Him say, "Where is Abel your brother?" and yet he dared, with the coolest impertinence, to reply to God, "I know not. Am I my brother's keeper?" As much as to say—"Do You think that I have to keep him as he keeps his sheep? Am I also a shepherd as he was and am I to take as much care of him as he did of a lame lamb?" The cool impudence of Cain is an indication of the state of heart which led up to his murdering his brother and it was also a part of the result of his having committed that terrible crime. He would not have proceeded to the cruel deed of bloodshed if he had not, first, cast off the fear of God and been ready to defy his Maker. Having committed murder, the hardening influence of sin upon Cain's mind must have been intense and so, at last, he was able to speak out to God's face what he felt within his heart and ask, "Am I my brother's keeper?" This goes a long way to explain what has puzzled some persons, namely, the amazing calmness with which great criminals will appear in the dock. I remember to have heard it said of one who had undoubtedly committed a very foul murder, that he looked like an innocent man. He stood up before his accusers as calmly and quietly, they said, as an innocent man would do.
