Politicians, preachers and pundits have long used the expression "my brother's keeper" as a persuasive for social involvement. But they don't understand what this expression means except that it is from the Bible which gives it an authority (No other book is used in this way).
"Am I my brother’s keeper?" Were the words of the first murderer. Cain, Adam and Eve’s first son, killed his brother Abel because he was jealous of him. And God, who of course knew what he had done, asked Cain, “Where is your brother?” And Cain mouthed off to the Almighty and said, “Am I my brother’s keeper?”
President Obama likes to say “I am my brother’s keeper and my sister’s keeper”. He thinks that is a good and noble thing, to keep and provide for people. Cain was the ultimate keeper of Abel; he kept him from living! I don’t want the president to be my keeper.
