15 But the LORD said to him, “All right then, if anyone kills Cain, Cain will be avenged seven times as much.” Then the LORD put a special mark on Cain so that no one who found him would strike him down. 16 So Cain went out from the presence of the LORD and lived in the land of Nod, east of Eden.
Cain Finds Mercy
Those who play with fire suffer burns. Cain failed to deal with the sin that threatened to devour his life (Gen. 4:7), and the eventual result was banishment from God’s presence. Why was Cain unable to turn from his sin? John tells us, “Cain . . . was of the evil one and brutally murdered his brother” (1 John 3:12). Victor Hamilton says, “His murder of Abel was an external manifestation of the grip that Satan had on his life.”
How do we underestimate the power of sin? What keeps us from repenting of our sin? What can be done to end the separation of the sinner from God?
“All right then” — the NET Bible’s translation of the opening word from God (Gen. 4:15) — is a bit trendy for a divine statement. God acknowledges the rightness of Cain’s fear of retaliatory death. The meaning of the original word is important in showing God’s attitude toward Cain’s request for relief from his punishment. This request from Cain is the very first cry for rescue from sin’s consequences in human history. If God is willing to listen to the requests of a murderer, then he will listen to ours as well!
God is willing only to give Cain special protection from the very kind of violence that Cain inflicted on Abel. Anyone who kills Cain will be avenged seven times as much as Abel. Wenham is probably right in saying, “Most probably it is a poetic turn of speech meaning full divine retribution.” But there is no protection for Cain from anything short of killing him.
Cain is the original “marked man,” but we do not know the manner of the sign that set him apart from others. Gordon Wenham cleverly observes, “As the clothing given to Adam and Eve after the fall (3:21) served to remind them of their sin and God’s mercy, so does the mark placed on Cain.” You might say that no one who encounters God comes away unchanged. Further, living around God is not safe if you live a life of disobedience.
Like Adam and Eve before him, Cain suffers exclusion from fellowship with the Lord (Gen. 4:16). Cain demonstrates the theme of degradation in his exclusion from humanity. Recall that Cain has been condemned to be a “homeless wanderer on the earth” (Gen. 4:12). The land of Nod is a place whose name is a variant of the word for “wanderer.” Hamilton says, “The wanderer ends up in the land of wandering.” Perhaps the naming of Nod after the punishment of Cain gives us a clue as to how widely people knew that God condemned Cain’s sin.
