11 So now you are prohibited from using the ground, which has opened its mouth to drink your brother’s blood from your hand.
12 When you try to work the ground, it will no longer produce for you what it is able. You will be a fugitive and a wanderer in the land.”
13 Cain said to the LORD, “My guilt is greater than I can carry.
14 See, you have driven me today away from the ground, from your face I will be hidden also. I will be a fugitive and a wanderer in the land, and whoever finds me will kill me.”
15 Then the LORD said to him, “Not so! If anyone kills Cain, he will be receive revenge seven times.” And the LORD put a mark on Cain, lest any who found him should attack him.
16 Then Cain went away from the presence of the LORD and he settled in the land of Nod, east of Eden.
17 Cain was intimate with his wife, and she conceived and gave birth to Enoch. When he built a city, he called the name of the city after the name of his son, Enoch.
18 To Enoch was born Irad, and Irad fathered Mehujael, and Mehujael was father of Methushael, and Methushael was father of Lamech.
19 And Lamech took two wives. The name of the one was Adah, and the name of the other Zillah.
20 Adah bore Jabal; he fathered those who live in tents and raise livestock.
21 His brother’s name was Jubal; he was father of all those who play the lyre and pipe.
22 Zillah also bore Tubal-cain; he was the forger of all instruments of bronze and iron. The sister of Tubal-cain was Naamah.
23 Lamech said to his wives: “Adah and Zillah, listen to my voice; you wives of Lamech, listen to what I say: I have killed a man for wounding me, a young man for striking me.
24 If Cain’s revenge is seven times, then Lamech’s is seventy-seven times.” _________________________________________
Some ridiculously think that Cain’s mark was a racial distinction. It was a mark upon Cain himself, as a warning to others, not to seek vengeance on him for his crime. God also used a mark in a later story (Ezekiel 9) to protect those from his own judgment of idolatry. The Beast in Revelation puts a mark on those who belong to him for the same reason, but it will not protect them from God’s judgments (Rev. 16:2; 19:20). Only those who have God’s mark are truly protected.
LORD, thank you for saving us by your grace, and protecting us from your wrath to come.
