Genesis 4:10
4:10 But the Lord said, “What have you done? 1 The voice 2 of your brother’s blood is crying out to me from the ground!
Genesis 27:22
27:22 So Jacob went over to his father Isaac, who felt him and said, “The voice is Jacob’s, but the hands are Esau’s.”
1 sn What have you done? Again the Lord’s question is rhetorical (see Gen 3:13), condemning Cain for his sin.
2 tn The word “voice” is a personification; the evidence of Abel’s shed blood condemns Cain, just as a human eyewitness would testify in court. For helpful insights, see G. von Rad, Biblical Interpretations in Preaching; and L. Morris, “The Biblical Use of the Term ‘Blood,’” JTS 6 (1955/56): 77-82.
