Genesis 4 contains the first murder in human history. It did not take long after the Fall and the Curse for the children of Adam to be enmeshed in sin, pride, disobedience, and false worship. Cain killed Abel, but the Lord still showed him mercy. Lamech, the first bigamist, boasted in killing a young man. The offspring of the woman appears all but lost. But the Lord revealed hope to humanity by giving another offspring, and through it, a better blood.
