What could be a logical interpretation of Genesis 4:15?
In Genesis 4:15 God executed an act which had benefited Cain, a murderer, by meting punishment seven times over to whosoever should kill him. Hence God put a mark on Cain to put an identification that the man should not be killed. My questions are:
1. What made Cain's existence so important that others would be punished seven time over for killing this murderer?
2. What is the mark that God put on Cain for anyone to identify him and thus will not kill him?
3. If God punished him to be a wanderer, is he alone in his wandering or is he wandering with his family?
