New King James Version (NKJV)
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.
