The harp and organ The word rendered organ here means a lovely instrument; but what kind of an instrument this was, the Jews themselves do not know. This Jubal was the inventor of such musical instruments, and of music itself.
Genesis 4:23. This passage is extremely obscure. We have no information whom he slew, or on what occasion, neither what ground he had to be so confident of the divine protection. The original words indeed may be rendered, Have I slain a man to my wounding? & c. And perhaps the best key to their meaning may be to suppose that his wives were convinced he had sinned in marrying them both, and introducing polygamy, and were afraid that the judgments of God would fall upon him for that crime, and upon themselves, for his sake. And he might say these words with a view to comfort them. As if he had said, Why should I fear, or you fear for me? Have I slain a man to my wounding? &c. That is, that I should deserve a wound or death to be inflicted on me? You have no cause to fear for me, or for yourselves on my account. For if Cain shall be avenged seven-fold If God engaged to protect him, although he murdered his innocent brother, he will much more defend me, who have committed no such wickedness.
