Notice the impressive plainness and fewness of the words. Cain rose up against his brother, and slew him.' A kind of horror-struck awe of the crime is audible. Observe the emphasis with which his brother' is repeated in the verse and throughout. Observe, also, the vivid light thrown by the story on the rise and progress of the sin. It begins with envy and jealousy. Cain was not wroth because his offering was rejected. What did he care for that? But what angered him was that his brother had what he had not. So selfishness was at the bottom, and that led on to envy, and that to hatred. Then comes a pause, in which God speaks remonstrance's,--as God's voice--conscience--does now to us all,--between the imagination and the act of evil. A real or a reigned reconciliation is effected. The brothers go in apparent harmony to the field. No new provocation appears, but the old feelings, kept down for a time, come in again with a rush, and Cain is swept away by them. Hatred left to work means murder. The heart is the source of all evil. Selfishness is the mother tincture out of which all sorts of sin can be made. Guard the thoughts, and keep down self, and the deeds will take care of themselves.
