Genesis 4:6-8 Tree of Life Version (TLV)
6 Then Adonai said to Cain, “Why are you angry? And why has your countenance fallen? 7 If you do well, it will lift. But if you do not do well, sin is crouching at the doorway. Its desire is for you, but you must master it.”
8 Cain spoke to Abel his brother. While they were in the field, Cain rose up against Abel his brother and killed him.
