The first born of Adam and Eve. His name is derived form Hanah, to possess. Hence Cain means, possession. And this agrees to Eve's name of her son, for she said, I have gotten a man from the Lord; or as it might be read, the man (that is the very one promised), from the Lord. (Genesis 4:1) Alas! how little did our poor mistaken mother know, what miseries among thousands and millions of her children would be induced, before He should arise to do away the evil of her transgression, by the sacrifice of himself!
