Genesis 4:8-13

8And Cain talked with Abel his brother: and it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him.

9And Yhwh said unto Cain, Where is Abel thy brother? And he said, I know not: Am I my brother’s keeper? 10And he said, What hast thou done? the voice of thy brother’s blood crieth unto me from the ground.1 11And now art thou cursed from the earth, which hath opened her mouth to receive thy brother’s blood from thy hand; 12When thou tillest the ground, it shall not henceforth yield unto thee her strength; a fugitive and a vagabond shalt thou be in the earth. 13And Cain said unto Yhwh, My punishment is greater than I can bear.2
