Genesis 4:8-10 New International Version - UK (NIVUK)
8 Now Cain said to his brother Abel, ‘Let’s go out to the field.’[a] While they were in the field, Cain attacked his brother Abel and killed him.
9 Then the Lord said to Cain, ‘Where is your brother Abel?’
‘I don’t know,’ he replied. ‘Am I my brother’s keeper?’
10 The Lord said, ‘What have you done? Listen! Your brother’s blood cries out to me from the ground.
