My Brother's Keeper
There are numerous "firsts" in the book of Genesis, from the creation of all things to the beginning of the Hebrew people. The account of Cain's killing of his brother Abel yields several such firsts. Usually it is pointed out that this was the first murder (which is true), but there are two much more important other firsts in this story. The foundation for these two is laid here, but they are more thoroughly developed in later scriptures.
