4:4. Abel also offered of the firstlings of his flock, and of their fat: and the Lord had respect to Abel, and to his offerings.
Had respect… That is, shewed his acceptance of his sacrifice (as coming from a heart full of devotion): and that, as we may suppose, by some visible token, such as sending fire from heaven upon his offerings.
4:5. But to Cain and his offerings he had no respect: and Cain was exceeding angry, and his countenance fell.
4:6. And the Lord said to him: Why art thou angry? and why is thy countenance fallen?
4:7. If thou do well, shalt thou not receive? but if ill, shall not sin forthwith be present at the door? but the lust thereof shall be under thee, and thou shalt have dominion over it.
4:8. And Cain said to Abel his brother: Let us go forth abroad. And when they were in the field, Cain rose up against his brother Abel, and slew him.
4:9. And the Lord said to Cain: Where is thy brother Abel? And he answered: I know not: am I my brother's keeper?
4:10. And he said to him: What hast thou done? the voice of thy brother's blood crieth to me from the earth.
4:11. Now therefore cursed shalt thou be upon the earth, which hath opened her mouth and recieved the blood of thy brother at thy hand.
4:12. When thou shalt till it, it shall not yield to thee its fruit: a fugitive and a vagabond shalt thou be upon the earth.
